Seems the highly fluctuating ratings of AbeBooks are caused by a lot of the reviews of AbeBooks which should be of the underlying independent sellers instead. AbeBooks is a portal for sellers of rare books, art, textbooks and more. AbeBooks is not the actual seller.I'd like to share my experience with one of these sellers, Noble Knight Games. NKB are the ones getting the five-star review. I (living in the Netherlands) ordered a series of rare, out-of-print, RPG books. The price was quite reasonable and the shipping costs (US to NL) was as expected. I opted for Priority Shipping. I received the books after 4 four days! And this included a one-day delay from the Dutch customs. The books were described as Used, but Very Good. One cover is slightly sun-damaged, but the rest are in near-mint condition. I cannot tell that they have ever been opened before. If you use AbeBook and the Seller is NKG, you're guaranteed high quality goods (unless description says otherwise) and timely delivery.
