Big Lots is a good choice but honestly I would say just check out as many gas stations, c-stores, supermarkets and any other place because you never know exactly what you're going to find. Out here in CT I always come across Monster, Rockstar, AMP, Full Throttle, Red Bull and SoBe's teas/juices but one day when I was checking out a place I've never been to they had about 75% of the Hansen's drinks and they had a good selection of Spike as well. Just get to some various places and you'll probably find a lot more than you knew was out there to begin with.
