We have switched entirely to grocery delivery for the last few months and have been pleased with the service.
You can access
Instacart directly through your computer browser; no phone app required. The website has a chat feature that allows customers to send and receive messages from their shoppers.
In our area, Instacart delivers from Publix, Sams Club, Target, Fresh Market, Aldi, BJ's Wholesale, Staples, CVS, Petco, ABC Liquor, and The Vitamin Shoppe.
There is a price markup so that items cost more than they do in the store. That, along with various fees and the driver tip, usually add around $25 to the price of an order. Our customer experience with Instacart has been good and orders are almost always delivered within the promised 2-hour window.
Walmart has its own delivery service. There are no price markups and you can get an annual subscription at $8/month for unlimited free delivery.
Grubhub and DoorDash are available for restaurant food.
