On-Line groceries don't offer much in the way of benefit for people living on their own. First there is the minimum order threshold, second there is the consume-by-date on any sensible quantity and third the alternative wheeze precludes shopping elsewhere. And where can you re-cycle your plastic bags? No not carriers, wrapping that says "re-cycle with carrier bags at supermarkets"

And there is the exersise of trotting down to the local Coop, how do you fake that?

On-Line groceries is a market share exercise, not a cost cutting tactic. With the squeeze on food prices exacerbated by Brexshit this also will make my grocery bill more expensive!

FWIW Morrison's cheapo oats is measurably cheaper than Coop which is waaaaay cheaper than Painsbury's. If you are time rich & money poor - you notice these things. And I bought my Magners pack today, Tuesday, ready for Towersey and claimed my 10% Tuesday discount.
