PlayStation Blog announced today that PSN cards will be available at more national retailers beginning in October. The cards will soon be available in $20 and $50 denominations at Wal-Mart, Best Buy and "select Sam's Club outlets." The cards will assist in destroying GPAs when they become available in November at Barnes & Noble College Bookstores.
Sony had previously announced that PSN cards are currently available at Blockbuster, AAFES and a few regional retailers. Yup, still no GameStop.
