According to Amazon: third-party sellers are independent sellers who offer a variety of new, used, refurbished, and collectible merchandise.
In simple words, third-party sellers use Amazon platform to sell they own merchandise, but they are not Amazon as such because they have their own stock and prices.

I usually bought books from third-party sellers because they have sometimes better prices than Amazon. They also sell books that are no longer in print, rare titles, collectible editions and so on. Since I'm not a millionaire, many of my books are second-hand, but that was never a problem to me, because some of them are in excellent condition and deserve a second opportunity to be loved.
The following list covers three of my favorite third-party sellers from Amazon. Please note that the first two sellers specialize in selling foreign books, mainly from Asia, that means that the estimated delivery time can be 1-3 weeks (without tracking number) if you choose the standard service as shipping method. If you are an impatient person, please choose expedited shipping with tracking number, even if you have to pay more.
