They should be. If Charleston Beer Exchange and Greenville Beer Exchange can get them, I would imagine any beer sales location in SC can get them. Spartanburg has a shop called Oasis that carries a lot of different beers. Asheville, if you don't mind running across the border, has Bruisin' Ales. They have a stellar selection of beers. There's the Growler Station in Greenville. Lots of places.
I like beer exploration too. The first thing I look for on a menu or in a bar is something I haven't tried. That's part of the fun of the beer world. There's so much out there right now it's impossible to keep up, so I just keep trying new things.
