Try to buy the Pentax DA 21 or 35 macro at B&H and report back, please.(3) I don't know of any other major on-line companies who force you to add it to you cart to show you the price.
At least from Europe, they only show the price for these when they are in the cart. They even have a rather similar disclaimer as Amazon.
Probably there are other items, too.
This is almost certainly wrong.My conclusion is that it's Amazon, and Amazon alone, that makes you do this.
