Not this again. Amazon does not do this in the way that you imply. They try to have a single page for a given item (not always successfully). On that page, different users may see an offer for the SAME item from a DIFFERENT merchant - the price is set by the merchant, not Amazon. If you don't like it (and if there is a choice) click on the "N more used & new" link close to the buy button to see all the offers from various merchants.
Amazon themselves DO NOT show different prices to different customers for the same item sold by the "primary" Amazon merchant. However, they also run a merchant called "Warehouse Deals" which is basically B-grade stock. Obviously this is cheaper, with limited availability.
