Maybe I am slow coming to this? But saw this tweet last night from my friend David Wolman where he was selling his book (The End of Money) through twitter. How cool is that! All you have to do is reply to the tweet with the word buy!
Ok, so you do have to sign up to Chirpify for your order to be processed, but once you are, all you have to do for future purchases is reply to a tweet with the word buy! So its like amazon one click purchasing on twitter.
Genius stuff. Think of the possibilities!
