No idea. I buy only when I need something and currently I don't need anything. Last thing that I bought was a bunch of bike gear (pump, water bottle, holder and tools) that came close to $100 and before that a number of DSLR lenses/accessories that were much much more expensive. Amazon still has EF 85mm f1.8 lens I ordered 3 weeks ago waiting to be shipped to me (I chose free shipping), I wonder how much of the delay is due to free shipping and how much is due to the fact that I placed an order at $355, and current price is $422. Maybe they are hoping I'll cancel. Fat chance.
