I cut my teeth buying records at Jerry's almost 20 years ago. Jerry's is a giant space which can be overwhelming if you are not used to large record stores. I advise taking a list. For a while I would visit the shop weekly and still find stuff in the genre and alphabet bins a little stagnant. I'm not saying you won't find anything there, but if you look for something a few times and don't find it - you probably won't find. Part of the reason is the prices are so good, stuff does not stay on the shelves. The best place to look is the new arrival bin. Unfortunately the best stuff never hits the shelve, you can find it on eBay.
