Cash Converters is a UK store group, specialising in second hand goods. You take goods you no longer want and they convert them into cash for you.
It is a favourite place for crack heads to offload stolen goods.
Jeez look at them crack heads, they have wogged that 50 inch flat screen and are blatantly carrying it over to Cash Converters in broad daylight. They are gonna get so nicked for that, mate. No wonder they call the fuckin place Crack Converters.
