The UK had a pretty good Android Pay deal recently, so now it's the US's turn to save some money. Not just one deal, but two, from Seamless, where anyone using Android Pay can save $15 off orders this month, and Eat24, in which $5 comes off every order above $10 until October 15.
The prerequisite to this is you need to use your Android phone to order, and download either the Seamless or Eat24 app, obviously depending which deal you're using. When paying, simply use Android Pay as the payment method and the deal will come into action. For Seamless, after ordering you will receive a $10 voucher off the next order, and after the second order, a $5 voucher. The former expires on October 31 and the second November 7. The Eat24 promotion ends on October 15, but can be used as many times as you want until then.
There's not much more to say, other than to get ordering, paying, and eating.
