Interesting offer but I don't believe Hero Academy is something I'd play as it seems to be heavily online based. On another note, I noticed you are from Cork which is somewhere I had recently discussed visiting in the future.
When you are talking value it is not. Portal 2 75% off is worth 15$ and so is Nuclear Dawn. However, I understand where you are coming from so it is ok.
LOL, Good luck using that sort of logic here.
Nuclear Dawn = Given away free & part of an indie bundle -> People are lucky to get $2 in value for it.
Coupons = Are NEVER worth their face value as then the person might as well just pay the difference if they want the game. Of course, the coupon is worth a ton less when people are giving it away (which they are regularly) and the person you are trading to has the game already.
I am not claiming that the coupon is worth it's face value. But in the actual prices of both items I had offered it was not a lowball. I was not talking about their trade values.
Note: I do not trade for TF2 items or betas. Also I generally have all the indie keys I would care for.
