While Amazon keeps reducing the price of storage, I don't think they have ever reduced the price of requests. :( I would have expected the cost of every component of a request (CPU, bandwidth, etc.) would have gone down over time, but it is still 1000 PUT/LISTs per $0.01 (or 10k GETs, also per $0.01). :(
(These request costs actually add up quite quickly: I spent something like $8k on PUT/LIST last month. At one point I found out a client library I was using made the horrible decision to verify the bucket existed with a LIST request each time you made a connection; I tracked that down to $70/day I was losing.)
