I started brewing about 3 years ago and I come here for the majority of my supplies. The employees are generally nice and helpful, but you'll need to ask them for help. When I started coming here, they would offer alternatives if they didn't have what I was looking for. Now they'll just tell me they're out of stock or don't carry that item. Nobody has ever been rude, but customer service doesn't seem to be their forte. Prices and selection are good though.
Bottom line: you'll probably find what you want, but don't expect a smile along with it.
