Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
New subscribers saw a standard first-order offer. At a CPA of about $25, each customer took around 2.5 months to become profitable.
Variant
The offer was framed as 'Double Your First Order', a close cousin of buy-one-get-one with different wording.
Why it likely won
Our reading of the result, not the practitioner's claim.
- 'Double' is a simple, concrete promise that is easy to grasp in an ad or on a landing page.
- It raises the value of the first order without cutting the price, which may protect how the product is perceived.
- A stronger first offer helps most with cold paid traffic that has no reason to trust the brand yet.
Caveats: This was a before-and-after change, not a stated split test, so other changes in the same period may have contributed. The data is from 2015, and no sample size was shared.

How to run this test on your store
- Hypothesis
- If we frame the first subscription order as 'Double Your First Order', then more visitors will subscribe because the first purchase feels like more value for the same price.
- Primary metric
- Cost per acquisition
- Guardrails
- Cancellation rate after first order
- Gross margin on first order
- Active subscribers at 90 days
- Who should test it
- Subscription brands with low unit costs and slow payback on ads. It is less likely to fit products with thin margins or where customers don't want twice the amount.
Questions
What is a 'double your first order' offer?
New subscribers get twice the usual amount on their first delivery for the normal price. It works like buy-one-get-one with different wording.
Does doubling the first order hurt profit?
It costs one extra unit per new customer.
Here CPA fell from about $25 to $13, which more than covered that cost, but check your own margins.
How long should I watch a subscription offer test?
Long enough to see renewals, not just first orders.
A strong first offer only pays if subscribers stay.
