I sent in 6 books and got a quote for $67.95. The day after I sent the books out with the label they provided me (which wasn't even enough to cover shipping the books so I ended up having to pay $3.50 for shipping even though it was supposed to be free) they hanged my quote down to $0.47. They have no phone number so I contacted them through email. They said I didn't send the books and they only got 1 book. How does 1 book woeful over 15lbs!?!? Nothing I can do about it since the only proof I have is the original quote they provided me. Anyway DO NOT USE THEM! Oh and they never even paid me the $0.44 either.
