If you have
Amazon Prime, you can get free Grubhub+ for a year.
Some credit cards give you free Doordash for a year.
But getting those services for "free" is a little misleading. If your order is large enough, the "delivery fee" will be reduced to zero. But there is still a service fee. There is still tax. And you should tip your driver. So it's not like you're only paying for the menu price on the food.
Grubhub and Doordash might stop at places like Walgreens. If you put in what your Orlando address will be for your delivery address, you should be able to see if they will deliver from those places. But I don't know if you are limited to snacks or if you can order anything the store sells.
PP mentioned signing up for a 30 day trial account of
Walmart+ and then canceling it before your 30 days are up.
There are ways to get Instacart for free for a limited period of time or for a limited number of deliveries; they will deliver from Publix.
I'm not sure what in particular you want from Wawa that you can't get from Walmart or Publix.
