I have been a Kindle Unlimited member for many years. Because of this, I pay a monthly fee and can borrow or purchase books at a discounted rate. This was fine, and the administration even stated that the monthly fee was equivalent to the amount I would spend on the purchase price of a book. Now, with this verified purchase stamp, it is no longer true. Amazon will not mark your purchase as verified if you acquire it at a discounted price, and therefore, OBC will not process your review for payment. I have sent screenshots of my invoices and copies of the Amazon reviews to Admin, but to no avail. I have a couple of hundred dollars worth of reviews that are just sitting there in limbo. I am recommending that for Kindle Unlimited members to be able to get paid for their reviews, which they worked so hard for and followed all of the rules. If you have proof that you purchased the book and wrote the review on Amazon, that will be enough.
