I am the new Online Campaign Coordinator for a major web commerce site.
My task is also to improve the UX and improve sales.
Unfortunately there is no upsell option for a buyer when he chooses a product.
Do you guys have any experience with when to add such an option? Should it be listed together with the product before being chosen or after the product has been bought?
I have the attached following screen shots of what I want to A/B test.
