Hey everyone, I just thought it is worth pointing out that one of the possible prizes from Subway's current promotion is a 3 month PS+ subscription. I ate there once last week to try out the UC3 beta (which I sucked at since I never played UC2 multiplayer and the other team was a clan) and also got the UC3 dynamic theme. The codes below are free codes you can use on their website (multi-use; thanks to posters in the home thread for most of these), and I won the PS+ extension with one of them. So, I made back more than the money spent on the food, since I would've added more time eventually anyway .

I think that's just what they call these codes. The codes are on drinks, footlongs, and chips, and some were from elsewhere (not sure where they came from, but these were in the PSHome forum thread about Subway). The codes that come with food give you a guaranteed prize that you get to choose - beta acces, theme, etc. - as well as the chance to win something else.
