It is common to see items on the B&H site that are either B&H imported and warranted or USA manufacturer's warranted. For me, the price difference does not justify the risk. I have yet to have a failure within the warranty period, but I'm unwilling to take that risk, especially to save a $100 on a $5,000 piece of equipment. In the case of Nikon, a gray market piece of equipment does not have a manufacturer's warranty and will be warranted by the importer. I trust B&H to stand behind their sales, but not a lot of other retailers. You might investigate membership in an association that offers equipment discounts through certain vendors. For example, NANPA, the North American Nature Photography Association arranges discounts through Hunt's Photo in Boston. Hunt's is a reputable retailer and as a NANPA member, you'll get an account executive at Hunt's to handle your business. If you qualify for membership in ASMP, you'll get an across the board discount at B&H. The memberships get fairly expensive, so you have to get more benefit from membership than just an equipment discount.
