I'm certainly in the (b) category. I don't have to have most things right away. I have a list of things that check pricing on frequently, and when the price is right, I buy. Sometimes I never buy because the price never meets the threshold. Of course, that's only for things I desire, and don't necessarily need.

Of course, as morley pointed out in a separate reply, this seems like it may only be limited to art and memorabilia, which tend not to have a set value. If limited to these types of items, then Amazon's approach may make sense.
