SULT Subscription Rewards: Free Gifts, Credit and How It Works

SULT, the UK electrolyte sachet brand, doesn't describe a points or tiers program on its site. Its rewards sit inside its subscription: SULT lists five free gifts timed to the delivery number, a free SULT bottle on the 2nd delivery, a SULT 'TINNY' tin on the 3rd, £5 credit on the 4th, £10 credit on the 6th and exclusive events and collections for all subscribers. The subscription also costs £26 a pack against £31 to buy once, with free UK delivery on every order, and SULT lists the gifts as worth £50+.

Last checked against SULT's SULT Electrolytes product page, shipping policy and refund policy, all as of 24 October 2026. Prices are in pounds sterling on SULT's UK store. SULT's terms of service carry no subscription or gift terms and no last updated date.

SULT subscription rewards at a glance

The plan and pack selector on SULT's product page as of 24 October 2026.

How the SULT subscription works

SULT's subscription is set up on its SULT Electrolytes product page. Step 1 is to choose a plan: Subscription or Buy once. Step 2 is to choose a pack count and flavours. Each pack contains 26 sachets, and the flavours listed are Watermelon Berry, Peach Citrus and Mango Tropical.

On the Subscription plan the price is £26.00 against a struck-through £31.00, with a "Save £8.99" badge. Savings grow with pack count: one pack saves £8.99, three packs save £18.99 and six packs, marked best value, save £33.99. The £8.99 matches the £5 price difference plus the £3.99 UK delivery fee SULT lists, though the page doesn't itemise it.

The plan panel also lists four benefits: easily pause, cancel or adjust at any time, a 30 day money back guarantee, free gifts worth £50+ and free UK delivery every order. A dropdown sets how often a delivery arrives: every 4 weeks (marked most popular), 3, 6, 8 or 12 weeks.

SULT's shipping policy adds that UK orders typically arrive in 1 to 3 business days, that one-time purchases pay a standard fee calculated at checkout, and that EU orders ship at a flat £8.99.

The 5 Free Gifts, delivery by delivery

Under the frequency dropdown, the Subscription panel carries a "5 Free Gifts" strip of cards. Each shows the gift, its normal value struck through, a green FREE tag and when it arrives.

The strip scrolls sideways, so the £10 credit on the 6th delivery sits off screen until you move it. The first screenshot below shows the strip as it loads, the second shows it scrolled to the end.

The four priced gifts add up to £37.99 at SULT's own values: £15 for the bottle, £7.99 for the tin, £5 and £10 in credit. The panel's headline says "worth £50+", and the page doesn't say what makes up the difference, since the events and collections carry no price.

The gifts follow the subscription's delivery count, not how much a member spends. The page doesn't mention pack size, flavour or order value in connection with any gift. The "5 Free Gifts" panel appears when Subscription is selected and not when Buy once is. The flavour section carries a separate "Free bottle included" line, and the page doesn't say what triggers it.

What SULT doesn't publish

SULT's pages leave several details open:

• What counts as a delivery, including whether paused or skipped deliveries count.
• How gifts reach members: in the box, sent separately or claimed in an account.
• How the credit works: whether it is added automatically or applied by the member, whether it expires, and whether it can be used alongside other offers.
• What "Exclusive Events + Collections" are, how often they happen and how access works.
• What happens to the delivery count and the gifts if a member cancels, pauses or resubscribes.
• Whether any gift depends on pack size or flavour.
• Anything after the 6th delivery.
• A dedicated subscription terms page or FAQ. The terms of service on SULT's site cover the store generally and say nothing about subscription gifts or credit.

The fine print

• The gifts are listed against delivery numbers, so a member needs to stay subscribed to reach each one. SULT says you can pause, cancel or adjust at any time.
• Credit is listed as "£5 Credit" and "£10 Credit". SULT doesn't publish how it is applied or whether it expires.
• Free UK delivery applies to subscription orders. The shipping policy says one-time UK purchases pay a standard fee calculated at checkout, and EU orders cost a flat £8.99.
• The product page offers a 30 day money back guarantee. SULT's refund policy says returns are accepted on unopened boxes within 14 days of delivery and that opened boxes can't be returned. The two pages don't refer to each other, so check both before relying on either.
• The refund policy also says SULT can issue store credit instead of a refund if you ask when you contact them.

What stands out about SULT's subscription rewards

The reward ladder sits in the buy box. The gifts are not tucked into an account area or a terms page. They appear inside the Subscription panel, beside the price, with struck-through values, so a shopper sees what staying subscribed leads to before the first payment.

It mixes things and money. The two physical gifts come first, on the 2nd and 3rd deliveries, and the credit follows on the 4th and 6th. Credit has to be spent on a later order, so it gives a reason to buy again, where a bottle or tin is simply received.

It rewards deliveries, not spend. Nothing on the page links a gift to pack size or order value. Each gift is described by delivery number alone, which keeps the promise simple to state.

It is front loaded. Every dated gift arrives by the 6th delivery, and the page lists nothing after that.

What members should know going in:

• The gifts depend on staying subscribed. They are tied to delivery numbers, and SULT doesn't publish what happens to them if you cancel or pause.
• Credit rules aren't public. Expiry and how credit is applied aren't stated.
• The guarantee and the refund policy differ. The product page says 30 days, the refund policy says 14 days for unopened boxes.
• The £50+ headline isn't itemised. The priced gifts total £37.99.

Is the SULT subscription worth it?

If you drink one pack every four weeks, the subscription costs less on the page's own numbers. Six deliveries at £26 come to £156. Six one-time packs at £31 plus the £3.99 delivery fee listed on the page come to £209.94, a £53.94 difference before any gift. That is our own arithmetic from SULT's listed prices, and it assumes one pack per delivery.

The gifts add to that if you stay subscribed through the 6th delivery: a bottle, a tin and £15 of credit, plus the events and collections. The credit is only useful if you'll buy from SULT again, and SULT doesn't publish its rules.

If you only want to try SULT once, the gifts aren't the reason to subscribe, because the first gift arrives on the 2nd delivery. In that case the guarantee and the 14 day unopened return rule are what to check. If you buy electrolytes on a regular rhythm anyway, the subscription lines up with that and the gifts are a bonus.

What Shopify brands can learn from SULT's subscription rewards

SULT's setup is simple to describe and tied closely to how a subscription works. Four ideas travel well:

1. Reward the renewal count. A gift on the 2nd delivery rewards the first time a member lets the subscription renew. Subscription rewards can follow the delivery number, not only spend.
2. Show the ladder where the decision is made. SULT puts the gifts, their values and their timing in the buy box. Members compare the subscription with buying once with the whole reward path in view.
3. Mix low cost gifts with credit. A branded bottle or tin is a modest gift that carries your logo, and credit gives members a reason to place another order. Using both gives each milestone a different feel.
4. Decide what comes after the last milestone. SULT's page lists nothing after the 6th delivery. If you build a ladder, decide whether it ends, repeats or hands over to a points or tier program, and whether one-time buyers get any of it.

For the full story of how SULT grew, including its ads, funnel and retention, see our SULT playbook.

If you want to build delivery milestones like this on Shopify, Mage connects to your subscription app rather than replacing it. Mage works with Loop, Recharge, Skio and other apps built on Shopify's own subscription billing, and its Subscription Milestone earning rule rewards a customer once a subscription reaches a set number of successful payments, for example after their 6th monthly delivery. You set the renewal threshold and the reward to award, and an optional approval delay. The award is made once per subscription. A subscription that is cancelled before the threshold earns nothing, and a customer who cancels and later resubscribes starts again from zero.

Here is how a brand could shape SULT's ladder with Mage's features. SULT doesn't publish how it delivers its own gifts, so this is one way to build it, not a description of its setup:

• Free product on a delivery. Set a milestone for the delivery number you want, award the points that cover a Free Product reward, and let the member redeem it. Mage's Free Product reward gives a unique code that makes one unit free, and its optional seamless mode adds the product to the cart and applies the code in one click. The member redeems the gift on an order, so it works as a claimed reward rather than an item packed into the next box.
• Credit on a delivery. In a points program, award points equal to a fixed amount reward, for example a £5 off reward. In a store credit program, Mage's earning rules award store credit directly, and the member applies the balance at checkout. Store credit in Mage is its own balance, not Shopify's native store credit. A program in store credit mode has one reward type, store credit redemption, so a brand using free product rewards would run points mode instead.
• Subscriber-only events. A Custom reward, available on the Growth plan and above, covers something you fulfil yourself such as an event invitation, with no discount code.
• Several milestones. The help docs describe the renewal threshold for each Subscription Milestone rule. To lay out a full ladder of 2nd, 3rd, 4th and 6th deliveries, the Mage team can confirm the best way to set it up for your plan, and custom actions (Growth and above) let your backend trigger awards through the REST API or Shopify Flow.
• Keep rewarding after the last gift. Points, VIP tiers and referrals sit alongside subscription milestones, so subscribers and one-time buyers can both keep earning.

If you're building a Shopify loyalty program around a subscription, Mage can connect the two.
