Sweaty: When the Pack Size Is the Subscription Interval.

How Sweaty sizes a 24-sachet box to exactly one month and then offers exactly one subscription interval, leaving flavour as the only choice a subscriber has to make.

Why Hydration Fits Subscriptions

Electrolyte powder is one of the few consumables where the packaging counts itself down. A sachet is one serving, a box holds a fixed number of them, and the pile shrinks on the counter every morning. There is no half-empty tub that might mean two more weeks or two more days.

  • Use is daily, not occasional. Hydration is taken as a routine rather than a response, so consumption barely moves week to week.
  • The habit attaches to a time of day. A powder taken on waking or after training rides on something the customer already does.
  • Flavour wears out before the benefit does. People stop a daily drink because they are bored of it, not because it stopped working. Variety is retention here, not merchandising.

Sweaty’s Strategy

The catalogue is five products. Three are hydration mixes — raspberry, citrus, and orange and mango — sold as 24-sachet boxes at €29.95 each. The other two are water bottles at €8.95 and €10.95.

Only the three mixes carry a subscription, and that subscription offers one interval: every month. There is no six-week option, no quarterly, no larger box. All three flavours cost the same, so switching between them costs nothing and compares to nothing.

Sweaty removed every variable from the subscription except the one that keeps a daily drink from getting boring.

The bottles sit outside the plan entirely. That is what you would expect from a durable, and it is worth saying only because plenty of stores put one on a schedule anyway.

What Makes It Work

  • The pack size does the scheduling. Twenty-four sachets at one a day is a month. The interval is not something the store had to design; it fell out of the box.
  • One interval removes a decision at the worst moment. Every extra option on a purchase form is another reason to close the tab. Sweaty asks for a flavour and nothing else.
  • Equal pricing makes flavour a free choice. When all three cost the same, switching is about taste rather than value. A subscriber who switches is a subscriber who stayed.
  • The durable stays out of the plan. A water bottle delivered monthly is a returns problem, not revenue.

Key Takeaways

If you sell a single-format consumable — sachets, pods, bars, anything counted out one unit at a time:

  • Size the pack to the interval you want. A box that lasts a month makes a monthly plan obvious, and you never have to explain it.
  • Offer one interval when one is honest. Interval menus belong to catalogues where consumption really varies. Elsewhere they add a decision.
  • Price every variant the same. Then switching is a taste choice, not a value comparison you might lose.
  • Keep durables off the plan. Nobody needs a second bottle next month, and the cancel it triggers takes the whole subscription.

Build This with Joy Subscriptions

Here is how to build Sweaty’s one-decision plan with Joy Subscriptions on Shopify:

  • Subscribe & Save - Put a single monthly plan on the consumable pages and leave the accessories as one-time products.
  • Build-a-Box - Let a subscriber fill one box from all three flavours, so variety happens inside the plan instead of triggering a cancel.
  • Customer portal - Subscribers switch flavour, skip a month or pause without emailing anyone. A one-interval plan needs that release valve.
  • Subscription analytics - Watch how many subscribers change flavour before they cancel. That number tells you whether variety is doing the retaining.

Start with one interval and add a second only when the data asks for it. Free Forever covers the first 50 active subscriptions with no transaction fee, which is enough to learn whether a single monthly plan holds.

Frequently asked questions.

How many subscription intervals should a store offer?+
As many as consumption genuinely varies, and no more. A catalogue of different sizes and use rates needs a menu, because one schedule cannot fit a 2kg bag and a 12kg one. A single-format product does not: Sweaty sells one box size holding 24 sachets, which at one a day is a month, so a monthly plan is the only honest option and the only one it offers. Every extra interval past that is a decision the customer has to make on a purchase form.
Should subscription variants be priced differently?+
Not if you want customers switching between them. Sweaty prices all three flavours at the same amount, which makes changing flavour a question of taste rather than a value comparison. That matters because flavour fatigue is what ends a daily drink subscription. A subscriber who switches is a subscriber who stayed, and a price gap between variants gives them a reason to stop and reconsider the whole plan instead.
Should accessories be available on subscription?+
No. A durable does not deplete, so a recurring order for one generates unwanted deliveries and then a cancellation that takes the whole subscription with it. Sweaty keeps its two water bottles as one-time purchases and puts plans only on the sachets. In Joy Subscriptions you attach selling plans per product, so the consumables can subscribe while the hardware stays a single sale.
