Here’s what consumers have asked with answers from Paper Cavalier staff and previous consumers.
Very deceptive. You think you are actually getting some rare book they have because that's what their website says. They sell on Amazon and they buy on Amazon. You buy from them, and they just buy from another real seller. Like I couldn't have done that. Helloo...
You can get whatever book you want, as long as someone else has it! They don't have any books, so if you buy from them you just have to wait a little longer, while they get it from someone else (and mark it up before selling to you.) International sellers just need to look beyond Amazon to get international shipping.
