It is more than likely the repricer. Amazon will remove prices eventually. The reason nobody catches these is that they are slow moving books. We used to only clean them up once a week sometimes as much as once a month. It happens with all the repricing software. Some are better than others and you can always add caps. I think our cap was $4000. You have to set the cap that high because there are certain architectural, medical, and occasionally historical texts or sets that will run this high. ...and books are a volume game. The more you process the more you sell. Software generally used... Monsoon Fillz SellerCentral NeatoScan Thrift books (close to the largest is primarily in house software). When I worked there we ran close to 120k skus (sku = ean, condition combo). We were not the largest but, for a time in the top 10% of third party new and used book sellers. We got our books from remainders, closeouts, and auction. Most of the time we could process ~15-25 pallets/gaylords of books per week. It's a repricing issue that no one has caught yet because it's a crappy title and no one is worried about losing a sale. Titles with a rank of < 10k are monitored daily for mispricing issues. Other than that...scan more books, get them listed, it's all about the numbers.
