As much as I like Sam & Max, I'm not paying $54 for an $18 T-shirt. Surely shipping a T-shirt across the pond shouldn't have to cost $36? For that money I expect it to be delivered within twelve hours after ordering on a gold platter.
Though in fact I'm not expecting it to arrive at all because at that price I sure as hell am not going to buy it. And neither will the other 99,99% of the Sam & Max fans not living in the US, I expect.
