Have you played with Online's bucket service, C14 [0]? They seem to have the lowest pricing on the market.

While not priced per GB used, hubic.com is the cheapest storage I know at 50€ per year for 10TB in the biggest package. Uses the Openstack Swift API.

Edit: "unlimited" Services are even cheaper on paper of course, but i don't really trust those.
