De-duplication of orders on merchandizing eVars is not done
consistently. If I do one purchase of two products, both using the same
value in a merchandizing eVar (let's say: "shirts"), then 1. I see two
orders for "shirts" in the eVar report (total line is 1) 2. When I do a
breakdown to products, I see only one purchase for "shirts". I do not
disagree with either result. But it would be nice if you could restrict
yourself to one method per report:-) so longnic
