I'm expecting at least Nikon lens and accessory prices to go up substantially in the US in the not too distant future. If you look at when some of these items were originally priced, Nikon has suffered very large product margin hits on many of these due to the currency exchange difference. I think it reasonable to expect a list price bump soon, then rebates again to move any inventory that sits around too long.
Ironically, here I am writing that I expect to see Nikon increase lens prices while at B&H we now have 10% instant rebates on the entire Sigma lens lineup (and free shipping for most of them, too). So what gives? Well, as I said in the last post, get ready for a bumpy ride. Inventories that have already piled up in the US due to our economic downturn need to be cleared. Incoming restocking of inventories need to be repriced to deal with the lower value of the dollar to the yen. Thus, we're currently seeing some deals that probably won't repeat soon.
