Twice this app has screwed me out of money. Most recently, the app offered me a 75% off discount which was applied to my order (the discount appeared in the calculated total), but when I completed the order, it went through without the discount applied. I tried to immediately cancel the order but was informed that there would be a $25 charge to do so. I recommend using a competing service Update: tempted by an 80% off promotion, this app screwed me again... with no food received. Unbelievable
