I tried that in the pandemic. The ordering sites were pants, the delivery times were missed, the selection of fresh products seemed like shifting old stock (and supermarket produce is never as fresh as markets anyway) and the substitutions were ridiculous. It's much less stress just to cycle to the High Street (well, mostly Broad Street, Norfolk Street and New Conduit).
This is bollocks, we pay about £4 for a delivery which is probably cheaper than driving to our nearest big supermarket. We have never had a delivery not be in the time allotted.
Just remind me when exactly the pandemic was, you might find things are a bit different now.
I can cycle for 6 hours plus but there’s no way I could carry our weekly shop back on my bike, in fact I couldn’t even carry our weeks wine.🥂
