GameStop has a reputation of upselling customers at the cash register. As annoying as incessantly turning down pre-orders and protection plans can be, though, it's child's play compared to what the brick-and-mortar videogame retail giant is expected to start pushing soon. GameStop is set to offer its own credit card to customers that ties directly into the company's PowerUp Rewards program, according to anonymous sources. We obtained photographs that outline the details of the card showing that the primary incentive for signing up is 5,000 bonus points for PowerUp Basic members and 15,000 bonus points for PowerUp Pro members. Also noted are exclusive offers to cardholders. The finer (and more important) terms of the GameStop credit card is that it will come packaged with an interest rate of 26.99%.
