I'm all about teaching people new things about bitcoin. So if you want to do a small dollar amount in a bitcoin transaction using Google Wallet then I'd be happy to walk you through it all. As you may know Google Wallet transactions can be reversed because they go through an intermediary who holds our cash. Bitcoin transactions can't be because they're direct (E.g. you instantly have the cash). So I need to have your ID and your written expression that you are purchasing this just in case you cancel your google wallet transaction and I need to get my money from Google.
