Depends...as the folks at Lensrentals.com have written, the camera business has changed, markedly, over the last few years. It used to be that
B&H almost always had the lowest price on any given lens, but as the Lensrental folks have stated, that is not true any more; at times
B&H prices will be higher than other vendors. A few years back, when Nikon's 200-400 f/4 VR zoom lens was the hot ticket,
B&H Photo had them for sale at $900 HIGHER than my local store, and I helped an internet forum member purchase his 200-400 from my local store at a huge savings. When I bought my 70-200 VR back when it first came out, I payed around $189 LESS for it locally than at
B&H. Why? Because
B&H has national name recognition, and has a huge backlog of customers who automatically assume that the
B&H price will be "the lowest possible fair price". Which, in these days of reduced stock availability, is NOT always the case. When demand is high, but supply is low,
B&H, or any other mega-dealer will often raise prices, as a way to,well, you know...
There are plenty of outlets across the USA at which to buy equipment.
B&H is a well-regarded retailer. But there are many,many other good retailers across the USA where fair prices, reasonable return policies, and excellent values are to be had. One thing to keep in mind is that the mega-dealers can sell used equipment at much higher prices than smaller outlets, where there is not such a huge pool of customers. If for example, you are in the market for a big-ticket item, like say a 300mm f/2.8 lens, you almost certainly will NOT get the best deal at a mega-store with nationwide advertising and a huge web presence, but in a much smaller market store, in a place like Dallas, Seattle,Portland, Omaha, Kansas City, Miami, Houston, Pittsburgh,of Minneapolis-St. Paul. There is a difference between walk-in retail prices and mega-store web pricing. In walk-in retail, a used or big-ticket item is worth what it is within THAT market; with a mega-store, the highest possible price can be tacked onto an item, and it will sit there until a willing buyer comes along and will pay top dollar.
