Pro Primarily sources used book stores
AbeBooks compiles prices from used book stores, acting much like eBay for used books.
Con Deceptive, unreliable merchants
Many users have complained about information inconsistencies, shipping problems, and wrongful refusal of refunds. The percentage of orders that are actually fulfilled is estimated to be about 20%. While this isn't always the fault of AbeBooks.com, it might just be a lack of proper oversight.
Con Slow delivery is common depending on the provider
It is not uncommon for books to take 3-5 weeks to be delivered.
