I just got an email from the shop owner stating that they have had two BTC transactions on the site already!
This has certainly gotten their attention/interest in Bitcoins. I also pasted them the link to the twitter comment about Shopify supporting BTC, so they ended up opening a ticket with them (Shopify) requesting BTC as a payment option!
If there are any other customers on Shopify that lurk this board - I would encourage you to do the same.
This is exactly the kind of thing we need to avoid BTC being considered "Fringe Drug Purchase/Money Laundering/Speculator" currency. Our media is sick and tends to focus on these stories so it will take 1000 good stories to counter every bad one.
