UberEats is free too, at least if you order a minimum. (Used to be $20 where I am, now it's $30.) Even when you pay a fee, it's only $4, which beats out BiteSquad's typical $10+ fee. In a contest for who can live the longest on tiny margins, I'm betting on Amazon -- hopefully they start signing up restaurants just a little bit east from Seattle so I can use them... When UberEats hiked their minimum I was a bit miffed.

Amazon is well versed in surviving on negative margins.
