wow then they give alot! in the states for a phat you would get maybe 25-30 bucks, and for games around 5 bucks each... but they only sell phats for like 60 bucks used, used lites are 90ish bucks or less... but rule of thumb is never to pay over half of what the thing cost new to buy it used from shops, private buyers are different, but you tend to get better deals from them anywho...
and yes EB is a major rip off in the states, much worse here... only buy from them if you absolutely have to, otherwise boycot them til they fold (wishful thinking)... and game store is worse, but they are UK owned...
