Folks in the UK and in major French cities have been able to do their food shopping online and have it delivered for a while. But if you live in a small French town, you haven’t been able to do that, until recently. Some supermarkets have started providing an online service recently. It works somewhat differently: they don’t deliver at home but you can order from your computer, and pick it up in your local shop, or in a purpose built warehouse near you.
I had meant to try this service for a while and I have at last done it. We have a Leclerc drive here. It’s not a shop, just a warehouse. You do your shopping online, decide when you want to pick it up, pay and print the receipt. Then, you go to the warehouse, scan the barcode on the receipt, and someone comes out of the building with your shopping and puts it in the boot.
