ARG, I just bought two lithographs last week. I could have at least saved $10 on the Meet the Medic print. So really I just payed $10 more instead of waiting a week. I guess I should be happy that the Portal 2 movie print is still $20 or else I would have been super ticked off. Anyway I'll get over it and be super stoked once I get them on Tuesday.
But for anyone still wanting to buy some stuff there the free Aperture lanyard deal is still good. "If you spend $20 or more on merchanidse, you can add a Aperture lanyard to your account and use the coupon code FREELANYARDFORSCIENCE at checkout to get a credit for the cost of the lanyard. Limit one per order. The Aperture lanyard promotional offer is valid through January 2nd."
I see the Valve Store as one of those places where buying a single thing sucks, but buying a lot is much easier to stomach. I didn't mind paying $10 for $40 worth of stuff personally.
