I had a terrible experience with B&H two Christmases ago and haven't been back.
They shipped an order (Toyo 4x5 camera kit), didn't bother to inform me that half (the lens) was backordered 'indefinitely' until everything else had arrived and I read the last packed invoice, took weeks to get them to send me a shipping label so I could send the camera back, several more to get a refund, then they tried to only refund half the money because I hadn't shipped back - wait for it - the lens that had been backordered indefinitely. In this two-month span they never had the camera kit listed as out-of-stock or backordered, always 'in-stock' even though I pointed it out at every phone call.
Since then I've avoided them like the plague. Their prices are decent, but no better than Adorama and some smaller retailers (KEH for used, J&C Photo, Badger Graphic, Midwest Photo Exchange) carry a better stock of the items I use.
