Don't bother selling it to a hobby shop. LGS's rarely give good value for bulk and in the case that they do, it's usually only for store credit. You're much better off selling online, either on eBay or Amazon. And if you haven't yet, I would suggest you go through your cards and check values. You could make a much better profit selling singletons on TCGplayer.com or StarCityGames.com, but that depends on what you've got.
