The hacks
Goal stack subscription instead of single-bottle subscribe
Subscribe to the Energy Stack (3 supplements) at 15% off recurring. The stack locks in $85/month vs $34 for a single bottle. Same daily routine for the customer, 2.5x the revenue for you.
Build-your-own supplement subscription stack
Let customers pick 3-5 supplements for their monthly auto-ship at a stacked discount. Tiergain handles cross-category stack selection with progressive pricing. The subscription app handles recurring billing.
Escalating subscription discounts for loyalty
Month 1-3: 12% off. Month 4-6: 15% off. Month 7+: 18% off. The escalating discount rewards loyalty without a points program. Customers stay because leaving means losing their earned discount.
Free trial-size of new product in every 3rd delivery
Every 3rd delivery includes a free trial-size of a new supplement. 38% of subscribers add it to their stack. The trial is the cheapest way to grow subscription AOV over time.
Subscription-only exclusive formulations
Offer a subscriber-only premium blend not available for one-time purchase. Exclusivity drives signups. Tiergain structures subscription bundles with exclusive product pools.
Post-purchase subscription conversion from stack buyers
After buying the goal stack, offer monthly auto-ship at 15% off. The customer just committed to a health goal. Converting while motivation is peak pulls the highest subscription rate in e-commerce.
Grow the subscription stack, not the subscriber count
Adding one product to an existing subscriber stack costs zero acquisition. That extra $25/month across 500 subscribers is $12,500/month in new recurring revenue from customers you already have.
