I can't check out unless I pay. How is that feedback?
Also, upvotes and merge decisions may well come from different people, who happen to disagree. This is in fact healthy sometimes.
- When I buy an item I still have to click a "check out" link to enter my address and actually pay for the item. I could take days after buying the item to click that link. - Some sellers might not accept PayPal, instead after I check out I get the sellers bank information and have to manually wire the money. I could take days after checking out to actually perform the money transfer.
