What about conversions that take some time to happen? The post didn't explain their typical/average time between first contact and sale. Assuming it's more than the 48 hours they ran this for, this experiment might still get better ROI numbers.
Are they tracking this metric? It's an important one!

- pierrefar 16y agoA really long-life cookie, say a 6 months or more. The concept: on the first visit, give the user a long-life cookie that stores the timestamp of the visit. When a sale happens, check the value of this cookie and store in a database. You can make it more elaborate by storing and analysing referral information, geolocation of the IP address, exact time of day and other things you think might be relevant. Also, if you're doing an A/B test on new visitors, this cookie should also store which version they were shown. This is a more complicated situation as to how you tie it into the A/B testing framework, but it's not hard with a bit of thought based on how you implement it and how you test.
