Hello!
In order not to miss anything and clarify all the points, we divide the answer into paragraphs.
1. To increase the rate, it was necessary to go to the promotion page and then place an order. Unfortunately, this transition was not.
2. During the processing of information, the store may change the order data. Usually reconciliation takes place before enrollment. The bonus is credited at a rate of 12% (10% + Letysilver status). That is, the cashback was not displayed correctly, but before the transfer, the amount became correct.
Respectfully,
LetyShops team
