wat do you use sp vouchers for??

People typically use them as gifts as far as I'm aware.

Yes, they're usually used as gifts. It's a way of sending pure sP, usually in relatively small amounts, between two people

Yeah.

Normally people set up trades and exchange worthless items for inappropriate amounts of SP in order to gift one another with sP, vouchers are a way to get small amounts of money over to someone. You can't send sP directly because of scamming dangers.
