So make your list price higher than your current price and let Amazon figure out what's best. Unless I'm missing something, Amazon's getting a percentage, so their income is maximized when your income is maximized.
You can't set the list price any higher than anywhere else.
i. List Price. The “List Price” for an App is an amount that does not exceed, at any time, the lowest list price or suggested retail price for such App (including any similar edition, version or release) available or previously available on any Similar Service or the lowest actual price at which you make or made such App available for sale through any Similar Service. You will update the List Price for each App as necessary to ensure that it meets the requirements of this section 5i.
You could just differentiate your product by releasing the Amazon super version that includes some trivial feature not available in the Android market version. Clearly such a feature is worth doubling the list price.
That's naieve. They have many products. They may use yours as a 'loss leader', they may experiment with your price, they may decide your product is worse than another one and position it as the low-tier offering and choose a price to enhance the sales of the higher-tier product (not yours).
