My daughter often spends so many hours working that she doesn’t even get time to go grocery shopping, and she will sometimes use Instacart to get her grocery shopping done, instead of going to the store herself. When we were staying at the airbnb in Washington, Robin and Laura bought our groceries using Instacart. It worked pretty easily, they just ordered and paid online, and pretty soon the delivery person showed up with bags of groceries. It looks like the way it works is similar to Uber, except for it is grocery shopping. The person who gets the delivery order goes to the store, shops for the items, and then delivers them to the designated address. If you order over $35, then delivery is $3.99, but if you become a member of Instacart ($10 a month) then , delivery is free (over $35). I downloaded the app, but I have not used it, and I don’t think that we would use it enough to justify the yearly membership cost. From what I read, you can choose which store you want to shop at, so you can still get your groceries from your favorite store. We usually just stop off at the grocery store on our way home from the fitness center when we need something, but I can see this as being a real blessing for people who live where there is bad weather/snowy roads, and things like that, where it is just not comfortable to drive somewhere and go shopping.
