Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsDave Diederen added a buy-one-get-one offer for a store whose audience loves deals, and average order value rose 25% to $105.42. This was a before/after comparison over four days, not a split test. Conversion rate and margin were not shared.
- Average order value: $105.42, up 25% vs the previous four days.
- Conversion rate, revenue per visitor and margin were not shared.
- A higher AOV from a free item does not by itself mean more profit.
The change
A buy-one-get-one offer is added; exact placement was not shared.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
Products sold at normal pricing with no BOGO deal. The comparison period was June 16-19, 2025.
Variant
A buy-one-get-one offer was introduced. The exact terms and where it appeared were not shared; the period measured was June 20-23, 2025.
Why it likely won
Our reading of the result, not the practitioner's claim.
- the audience already responded to deals, so a BOGO matched how they like to shop.
- a second item at no extra cost pushes shoppers toward two-unit orders, lifting AOV.
- a weekend launch may have drawn extra deal hunters, which can inflate a short before/after read.
Caveats: This is a four-day before/after comparison on a single store, not a split test. Seasonality, ad spend and margin impact are unknown.

How to run this test on your store
- Hypothesis
- If we offer buy one, get one to a deal-driven audience, then average order value will rise because shoppers are drawn to multi-unit orders that feel like a bargain.
- Primary metric
- Profit per visitor
- Guardrails
- Gross margin per order
- Conversion rate
- Refund rate
- Who should test it
- Stores with healthy margins and repeat-use products whose buyers respond to promotions. Premium brands or thin-margin products may lose more on margin than they gain in order size.
Questions
Does a BOGO offer increase average order value?
In this store, AOV rose 25% to $105.42 in the four days after the BOGO launched. It was a before/after check, not a split test.
Is BOGO right for every store?
Dave Diederen chose it because this audience was clearly deal-driven. Stores with thin margins should track profit, not just AOV.
