Given the reviews I had seen on this sight I didn't really want to take the chance and purchase anything from here, but an item was listed that had a great deal. It was a book that typically sells for over $45+ (originally $13 at retail but it was out of print and rare), selling on the site for $11. I thought, "wow, this is a really good deal", and figured I might as well risk it for the biscuit and see what happens.
Surprisingly, the book came and it was actually a copy of the book. HOWEVER, it was an ex-library book that was laminated by that said-library, which was not specified on the purchasing. I am a little disappointed at that fact, but I cannot deny that the price was great and all of the pages seem to be in tact.
I'm not 100% confident this is correct but I'm pretty sure this site is sort of like Amazon - personal sellers have the option to sell their volumes on it, so I think the quality is up to the sellers from there, not AbeBooks themselves
Overall, great deals for what it's worth, and I'm going to keep peeking at their manga collections for good deals!
