I already have most their comic books but I'll certainly get some stuff there, and for those that don't know them make sure you have a look at their webcomic: http://www.chickenwingscomics.com/
I am in no way related to them, and haven't even told them I would be advertising here. Hopefully they'll not get mad about it
From the newsletter:
The price of Bitcoin is volatile. In order to be fair to both parties and even out some of the short term spikes, we will look up the global average price of the day that you sent your email on bitcoinaverage.com and use the daily average exchange rate for our conversion.
Stef wanted to do this for over a year now, but those of us who know us, also know how slow we are with implementing changes in our website. But now that Bitcoin got a new level of publicity, we want to seize the opportunity to jump on the bandwagon. If we're late or early, time will tell, but we're intrigued by the idea of a truly decentralized global currency and wanted to contribute our tiny share to its success.
