Actually, this sounds fucking ridiculous, but it might work.
A mate of mine was online looking for a nice new pair of slippers and seen that people were selling their old slippers (presumably to perverts). Anyway, he thought "fuck it, I'm going to stick my old manky slippers up for sale and see what happens". He made 25 quid on them, more than what he paid for them.
We could have a scm slipper sale, with the proceeds going to Oncey's good cause.
