A store total **** sold how much, only the owner can know, can see only a month to receive the number of evaluation how much. And that's different from sales, where neither the seller nor the buyer has made an evaluation within the evaluation period, i.e., neither of the 2 parties has made an evaluation of a particular transaction, then the evaluation lapses and doesn't show up.
A buyer who makes more than 6 transactions in the same store in a month can only show 6 evaluations, the rest are not scored, and repeated purchases of the same connected product in a month are only scored once.
