I'll never give GrubHub a penny of my money. They have been caught a number of times posting fake restaurant profiles of legitimate restaurants that trick consumers into ordering through their service instead of directly from the restaurant's own website. (Here's one article explaining it - but Google it for yourselves and you'll see a lot of complaints and stories.) Even though they've been caught doing shady crap like this a LOT, they keep doing it because they get a big percentage of the order value in revenue. It's a horribly dishonest business model and I'll never use them.
