Amazon said it recently received many buyers' inquiries about the rules for the use of incentives such as cash back, coupons and discounts. Amazon allows sellers to use these incentives, provided that these incentives are open to Amazon's specific products.

It may lead to the improvement of product search ranking, making false comments, etc.ins video likes free
