Guns of Icarus Online costs $35 for America/dollar countries and $40 for Europe. Because of that, I'm looking not only for people to buy this as a group with but also someone to do the actual purchasing since it'd be cheaper.

That'd come out to $8.75 a person.

It's a 4-pack so there's four people total needed, and I already have one from a forum thread on SteamGifts here:

We need two more people. I could be persuaded to buy two copies if we're running out of time, because it's cheaper if we buy it today or tomorrow: It'll be 25% more expensive on the 29th or 30th.

EDIT: We got it, so this's done.
