If you have multiple websites in Magento you may want to have different prices for different websites in Magento. The problem is that the Magento price attribute is set to global but says website in the attribute manager. It is also not editable in the attribute manager. To fix this go to your admin section. System > Configuration > Catalog > Price and change the Catalog Price Scope from Global to Website.
Currently it appears it can only be done per website with this method and not per store. I actually do not think it will ever be done per store since store is still the same website so why offer two different prices.
