These scumbags are unprofessional and I will never buy from them again. They sold me a book. Good book. Arrived in mail fairly quickly. But I had asked immediately and politely for a simple receipt. They said since some people order books as gifts, they don't provide receipts. I told them it's not a damn gift, it's for me, please include a receipt. They said no. A simple receipt for a sale is standard and they flat out refused me. These people are scumbags.
