I seen that they have good reviews so I gave them a try but I am starting to think the reviews are fabricated and flooded to hide critical reviews. Bookrun tends to quote you high prices to get you to sell them your book. However, once you send them your books, they will end up paying you less than half of the original offer. Books were in great condition and they would claim the books are in poor condition so they will not pay original quote. If the books were high value and buy certain companies they automatically flag it as counterfeit so that they don't have to pay. I've never had the experience with other vendors. If I were you I'd avoid doing business with bookrun.
