It sounds as if you could do with re-assessing your shopping habits. To be honest I’m not sure buying once a week from a single source is terribly satisfying - so you may well be finding yourself disinclined to buy more of the same.
There was an article in one of the papers recently, gently mocking subscription culture - but that’s exactly my weekly / monthly routine.
Small weekly supermarket delivery of cupboard staples.
Substantial weekly veg box including milk, bread, eggs, muesli, honey, as well as fruit, veg, herbs and spices.
Two monthly delivery of whole foods - pulses, legumes, grains, bought in bulk.
Weekly coffee bean delivery.
Intermittent wine deliveries.
Etc. I’m still on top of all the ordering - but never feel any pressure to cover everything in one delivery.
