If you're only talking one carton, I wouldn't sweat it as far as price, it's not that much different at the airport or elsewhere. It's not a huge amount more there. Best price is probably the Prime Cash and Carry, by the Harley Davidson place. Not sure I would make a trip there just for that. (Despite the name, they DO take credit cards.) Eric just usually buys his at Grand Marche. If you're otherwise going to GM, just get them there, so you can put them in your checked suitcase on the way home, as compared to having to hand carry them, if you buy at the airport.
