Ever since PSN cards have made their release in the United States, the Canadian neighbors up north have been clamoring for them as well. According to a post on the PSU forums, it looks like gaming retailers, such as EB Games and Gamestop, in Canada are finally starting to receive distribution of the coveted PSN cards.
As shown in the image above, the top of the card’s back reads “Valid in Canada only. Terms of use listed below,” meaning Canadians with US accounts will not be able to use their newfound wealth to exploit the US video store. Hopefully SCE will grace the video store upon our Canadian friends soon.
