I get a spam email almost everyday about a promotion, and you would think that for a company that uses the majority of its advertisement to highlights promos that the codes would actually work but they almost never do?? Even if the promotions worked, it would still be more expensive than just picking the food up yourself because the delivery and taxes are completely outrageous (like sometimes 50-60% of the food cost) on top of the often already more expensive prices. You would hope that after splurging on just to get delivery that you could enjoy your food, but very few couriers actually check the order so it often comes wrong and its impossible to get a refund. They dont give out refunds because people abuse the system but Uber is a multi-BILLION dollar company–they can afford it. They could also afford to not pay their drivers poorly, charge ridiculous fees, or advertise false promotions. This company is so greedy its obvious they made their money by screwing people over.
