DoorDash is offering $7 off any $25 DoorDash order when you pay with PayPal for a limited time. To get this deal, you must save the offer to your PayPal account and choose to pay with PayPal at checkout and your offer will automatically be applied to your qualifying purchase. Discount will not appear when checking out in DoorDash but will show up on your Paypal receipt. Offering expires July 31, 2021, but add it to your account as soon as possible because it is limited to the first 71,000 users. 

DoorDash is also offering many users $10 off orders of $25 or more when you use the coupon code: 10NICE checkout for a limited time. This offer should be able to stack with the Paypal offer if you are able to meet both requirements.
