I was watching TV and they were showing an ad for a product.  At the end of the commercial they provided a number you can call to order it.  So I'm thinking "Okay, I call that number, go through a bunch of menu options, wait on hold for X number of minutes, get a person, create an account and/or give them my name, address, phone number, credit card number, expiration, security code, etc etc."  

However, with Bitcoin, they could just show a QR code and say "Send Bitcoin here, include a note with your address."  You press a couple buttons on your cell phone, and you are done in seconds.  They receive the Bitcoin along with your address, and can mail the product to you.

Probably be seeing this in the near future?
