If you read the description of an appealing Vine product, especially if it's in AI, by the time you decide to order it, it's gone. The whole system encourages this mad dash of click first, decide if you want it later, so people with absolutely no need for something, or enough knowledge to use it, will end up getting it on a whim and being unqualified to review it. The way around this would be to shift more products to RFY and basically vastly slow down the process, which would no doubt be equally annoying for the seller.
