Siliconera breaks down PSP game prices: PSN vs. Amazon

Siliconera has gone through the effort of taking all the PlayStation Store's digitally distributed PSP game prices and comparing them to the current cost for a UMD hard copy through Amazon. The list is eye-opening, with the prices shifting -- sometimes dramatically -- between which retail outlet offers the better price. It should be noted that third-party retailers selling through Amazon, which are used for some of the prices in the list, can seriously skew results (especially with the shipping cost added). Sony had previously mentioned it seeks to maintain "pricing parity" between its digital and boxed titles.
