That's awesome you're representing Canada. Good luck. I don't know anything about birmingham, but if you're near west or south west london, maybe we could blaze it up. It's possible.

Prices go from:
10 for 1.6-1.7
20 for 3.0-3.5
40 for 7.0
65-70 for 14
120-130 for 28g's.

Just make sure you look closely at any bud you buy, never pay before you get it etc.
