Hello,
Well, a review is not valid when no transaction number or an invalid transaction number is entered. The purposes of entering valid transaction information are so (a) the merchant (and we) know that the reviewer is a real customer, and (b) it opens the door for the merchant to hopefully resolve a customer's complaint.
Note: a transaction number can be any unique transaction number issued by the store, including but not limited to: order, invoice, RMA, quote, transaction via email (with complete documentation including headers for verification purposes).
Merchants' policies and reviews' policies are listed here:
