always buy a box, its a better deal. btw, if u read in the UK read this, as u might not know this but:
DO NOT BUY ANY TINS, BOOSTERS OR BOOSTER BOXES AT ASDA!!! ASDA BELONGS TO WAL-MART!
If u don't have money for booster boxes, buy at least 3-4 packs at a time, and if the shop owners are clever enough to put the boosters behind the counter so nobody steals `em, just ask if they can get out the ones at the very bottom. That's what I always do when i buy at Bosswells. btw, do u know any other shops in Oxford that sell cards? i know that there are cards at Woolworths and Toys 'r' Us? I don't like buyin' there - Poke' cards at WW r really rare, and at TrU sells them for 20p more(i wanna save money).
