IGDA Board of Directors:
>Many journalists have noted the unusual nature of Amazon’s current store terms, but little has been said about the potential implications of those terms. In brief: Amazon reserves the right to control the price of your games, as well as the right to pay you “the greater of 70% of the purchase price or 20% of the List Price.” While many other retailers, both physical and digital, also exert control over the price of products in their markets, we are not aware of any other retailer having a formal policy of paying a supplier just 20% of the supplier’s minimum list price without the supplier’s permission.

They don’t provide any source links to the Amazon information, but if this is true I can’t imagine why you would want to be in the Amazon store. Especially given this:

>And if you ever conduct even a temporary price promotion in another market, you must permanently lower your list price in Amazon’s market.

Yikes.
