One of my colleagues is upset that she can’t order delivery from her favorite Thai place. They don’t have a website, but they have a Facebook page you can Like, and she wants to be able to order via Facebook.
Facebook could offer this; I figure they probably only have to flip a couple switches. It seems like adding a commerce portal would be the logical next step for them.
I expect that you’ll have to put money into FB credits, then use those to pay for what you order though.
How’s this for a business plan? If you grow the ingredients in FarmVille, you can convert them to credits and use those to buy dinner.
I think we call it “A Byte to Eat.”
