Note on books: for printed books, Amazon uses the ISBN-10 as the product's ASIN. Looking up a book barcode such as 9780735211292 returns the ASIN 0735211299, which is the correct Amazon listing (amazon.com/dp/0735211299). Kindle and other editions have their own ASINs.

* Provide at least one value in the single field or the list field. Items are processed 5 at a time and each one is saved to the dataset as soon as it finishes. If an item fails, the run continues with the others and the failed items are listed in the FAILED_ITEMS record of the run's key-value store. When the run reaches your maximum cost per run, the remaining items are skipped.
