Any store that sells digital SLRs with interchangeable lenses will have a good supply of filters in many sizes (I don't know if that's a "real camera store," rather electronics/photo). I don't think you need to go to B&H to find a filter selection. Maybe a larger city, though...
Not really. Like I said, Best Buy is the only cameras store in my city of 200k, they sell basic low end DSLRs but I've never seen filters there. I looked online, filtered by in-stock at my local Best Buy, and they list 3 UV and one CPL in the following sizes: 52, 58 (the CPL), 72, and 77. Thats not a very useful selection for testing size.
