It's an odd problem. My partner insists on keeping a shopping list. But mostly I remember what we have in the fridge and store cupboard, as I frequently cook. I don't actually forget that many items when shopping. Toothpaste I don't keep in the fridge. Being able to have a quick glance remotely could help, but I'd probably then abandon trying to remember, and it would probably take me longer. My partner recently tried a little stretch of buying online and collecting from the store. But for me, it took all the fun out of shopping. I actually enjoy strutting the supermarket - and some domestic tasks. My partner likes certainty. I like mixing things up a little.
