Not a bad store, except that it is nearly impossible to even get someone to look your direction. The selection is what you would expect for a place that buys from people. It is inconsistent, but you can also find some pretty cool things. Prices are not bad and they often have deals if you buy multiple items.
I would say that they are better for movies than anything else; it is a pretty vast selection. It can be crowded and a bit messy. It seems like the employees are most of the problem here. The shelves can be really out of order and I have seen many times when the same item was listed at multiple different prices or had gunk and other stickers all over it. If you are patient and do not mind doing all the work yourself you can find decent deals; just be prepared to wait ages for anyone to help with things you cannot reach yourself.
