don't steal of ur paren't man, that's just scummy. best bet is try to flog that gift voucher to someone you know, or someone who'd understand ur situation. ask ur parents if you can do odd jobs around the house, get some money and buy as much as you can. if you can get ur daler to strap you a good bit then do it but makesure you can pay back. if you're a good stoner and you share ur smoke with ur mates then im sure they won't hesitate to get you stoned or ite you off a wee nick fer a couple o fills
