In one line

Storage is the dull part of the bill. Requests and outbound bytes are what actually surprise people.

What gets missed

PUT, COPY, POST and LIST run over ten times the per-request price of GET, and DELETE is free. Standard-IA rounds objects up to 128 KB and holds them 30 days; Glacier classes hold 90 days, Deep Archive 180.
