Seamless is an online delivery platform, now owned by Grubhub. The good news is that even if you’re a Grubhub customer you can still sign up and receive the $7 new customer coupon. To get the $7 off, visit the homepage and a popup will appear asking for an email. You will receive the coupon via email and you have two weeks to use the coupon. The min order is $15, so you could potentially get almost 50% your order.
