Poor Exchange Policy

I purchased 3 books from Reader's Warehouse and received them on the 29th of October (16 days ago). I just now noticed that I already had one of the books. I meant to buy a different title in the same series and confused two of them.

I called their offices and was told that since 7 days have passed, there can be no refund. I was even happy to take an exchange and pay the difference to buy another book but was told that's not possible after 7 days either.

I'm very unhappy that this is the policy for a book that was bought about ~2 weeks ago and is in perfect condition as I've not opened the package until now.

I will not be buying anything from Reader's Warehouse going forward as both Exclusive Books and Bargain Books would have allowed me to exchange one book for another and that is a much better customer experience for roughly the same price.

How can there be a return+exchange policy window of just 7 days for products that are ordered online? Almost all decent retail stores allow 30 days if not more than that. Especially in these pandemic times.

Very poor service.
