Hi! I wanted to buy the physical version of a webnovel today and found on the internet a seller who gave an incredibly low price for said novel, it's not that I want to be distrustful... But, how can I rectify the product I'll be buying is the original one?
All books should have an ISBN. Ask the seller for theirs so you can verify such a book actually exists. Maybe some photos of the book itself (is he selling as new or used?). If the website you found him on legit? Is there any kind of customer protection program in place?
