steam discount coupons for trade.

I have five discount coupons for trade. I'll take anything you offer include nothing or possibly even another discount coupon. I'd prefer to give to five different people but not against giving multiple to one person. the five i have include:

syder arcade- 75%
contagion- 50%
zigfrak- 50%
portal 2- 50%
frozen synapse- 75%
