Items for sale on Amazon can be sold by more than one seller or merchant. For example, the same camera might be sold by three different merchants or sellers. The following figure from Amazon's retail web site shows an example in which two merchants are selling the same book.

Notice that the merchants are selling the same book for different prices. In other examples, the same item might be offered in multiple conditions, such as New and Used.

Any item being sold is associated with an offer. An offer is a combination of price, condition, and vendor. For example, one offer might be Amazon selling the new book for $11.67. Therefore, to find an item's price, you return the offers made by the vendors selling the item.

Offer information is made available by the OfferSummary, Offers, and OfferFull response groups, which can be part of ItemLookup, ItemSearch, ListLookup, and SimilarityLookup requests.

	Note
	Sometimes, instead of a price, the string is returned, "Too Low to Display." This sometimes happens even though the price might be available on Amazon's retail web site. In these cases, the only way to see the actual price is to add the item to a remote shopping cart.
