Hey, sorry I haven't replied. haven't had a look at this thread of a couple of days
The place is kinda hard to find... I have just had a look, like, everywhere and I can't find their card Sorry
But can I describe where it is...
There's a National Stadium, behind MBK shopping centre... Behind that National Stadium there's a little area with lots of sport shops everywhere, most of them pretty expensive, like real prices and stuff, and most of them are all shitty fake shirts. But right where the gate to get in the National Stadium, there is a street there, and there's a really nice shop, white front, lots of shirts on the inside, the shirts that are on display should be the real ones, go in and ask the guy. The place is called Siam Soccer Stars in big red font. Hopefully you get the owner, he speaks English well.
Sorry I couldn't find the card :S
