Not it will not. However, you must be sure that when you offer your discounted products, you do not do so as part of an agreement where the customer has to leave a review.
This is why deciding to list/market your discounted Amazon products on LootHoot can be done with confidence as our members choose to leave reviews and are not obliged to.
Beware of using any service out there, that promises or guarantees their members will leave a review in exchange for your discounted product. By doing this, you are highly likely to put your Amazon Seller account in jeopardy.
