getting groceries during an isolation period

We are arriving back at Lakeside on Dec 30 and will be self-isolating for at least a week. During this period what are our options for getting food and other essentials?
Thanks for any suggestions.

First, thank you Sturdley for self-isolating

El Torito delivers free, for sure in Ajijic, between 10 and 3, I think.  Not sure their delivery area.  They deliver alcohol in addition to other items.  They open at 8am daily. Very responsive at their Whatsapp number.  
331 417 5254

Free deliveries from Costa Alegre seafood also very good, Whatsapp  331 242 9451  Also open at 8 daily.

There are the Costco "kids" for delivery, but that's weekly so may not help you for initial needs.  Also a couple (Kenny and Joe) who deliver from the main abastos; they have multiple delivery dates weekly, different days for meats, for veg, for bakery items.  

As Bob said, many restaurants have delivery, some free, some for a fee.  

Walmart has a pretty good website and fairly consistent on items delivered. One of their regular drivers is a kind, gentle old man, who seems to truly appreciate the work and tips.

Here's an easy way to start checking out restaurants that deliver. Essnap. Has menus for everything you click on (which are oddly hidden if the restaurant is not open at that time). Delivery rates depend on how far the restaurant is from where you are. https://www.essnap.menu/
