I have bought various electronics and camera accessories from B&H with no issues (related to B&H).

However, I buy all my new camera bodies and lenses direct from the manufacturer. I have found the price to be identical (or nearly so) to B&H, shipping to often be free and from time to time, without a local tax. If Nikon, Sigma, etc are selling as 'new' what are returns/refurbs then there is no hope in the system at all.

edit: grammar
