Not a particularly big deal: PS2 Cash Shop doesn't offer the same amounts that my friend saw on his PoxNora SC shop. 300, 6000 are missing. The big deal is: that buying 2 x 300 (600 for today) at GBP4 works out cheaper than 500 (1000) at 4GBP. Not sure if this is the case for our US and EU friends - but UK folk, don't miss out!
i try desperately to get one of those $15 gamespot cards from the US, but either they refuse to read the card number over the phone OR they never even heard about it... it blows because you not only get 3000SC for $15 but a free weapon, and there is no tax on the $15
