Use code QUINNXCII.
Shows you need $15 but I got it to work on an order below $5.
Order must be at least $15 (before tax, tip, and fees). Non-transferable. Only valid for personal (non-corporate) accounts. Available for delivery orders only. Not valid for catering orders. Subject to restaurant and/or delivery availability. To redeem, click on the link above or enter code QUINNXCII at checkout on a qualifying order. Available on the Grubhub app only. For one-time use only. Cannot be combined with other discounts or cash. Expires 10/01/20 at 10 PM ET. May not be applied toward purchases containing alcohol.
Seems there's a code for tomorrow and the next day.
Ymmv.
