We've just added Bitcoin payment support to Poyomi
, print on demand service for Photo Books and Calendars. We ship worldwide and are really focused on ease of use and low prices. Give it a try, you can get a Letter 20 page photo book for just $6.99. Use the coupon code BITCOIN for a 10% discount. You can see our current BTC exchange rate on this page
(MTGox 24h average).
On the technical side of things, our site is implemented in C#/ASP.NET MVC with async processing for almost everything, including Bitcoin transactions. If anyone is interested, I can share some notes regarding integrating bitcoind with C#. We don't rely on third parties for BTC processing.
