Coupons: I won't use them, so going free if anyone can use them, just request.
Cards: 1for1 trading will always be accepted if you can offer missing on any badge I have under level 5, others depending on value both sides so be fair.

RULES: I will prioritise friends over 'dibs'; if I don't instant accept, I'll do it when I wake up/finish work/whatever, chill; ask if it's not listed above, but accept a 'no'.
