This is the same in the UK, all major grocery stores (Tesco, Sainsbury's, Asda, Morrissons, Waitrose/Ocado) all allow you to order and either collect for free or have them delivered for between £2.50 and £5 depending on the delivery time. I can't see Instacart having a market outside of the US and even then major stores will start to offer their own delivery services with no price bump which will put Instacart out of business, at least at any reasonable size.
