What percentage of a grocery store's inventory is perishable? There's plenty that has a pretty long shelf life. E.g. canned goods, paper towels, bathroom tissue, bottled goods, vacuum-sealed items, etc.
A lot of perishables (food, medicine, gasoline) get "outdated" pretty fast. Sure, as a concept, lettuce will stay with us for a long time. But an individual Bibb head won't last long, even under perfect conditions.
Cabbage, for instance, keeps longer than lettuce. Pluots keep, too, much better than peaches. Oranges, tangerines, and grapes keep well. Carrots keep pretty much forever.
For non-perishable goods sure. Buy those in bulk (based on your storage capacity) and have them delivered.
Buying highly perishable items once a week tends to result in a fair bit of wastage unless you're a whizz at meal planning.
For one thing, I've yet to come across bread with genuine flavour and perfect texture that lasts more than 3 days.
This method definitely keeps things fresh (no pun intended)! My kids are really good about eating fresh produce but I've noticed that they also appreciate rotating new things in every few weeks/months.
Right, and also stuff that doesn't keep well anyway. Seasonality or needing to ship quickly to avoid spoilage aren't problems for potatoes either; if well-climate-controlled they keep for months.
There's a practical reason for this. Temperature and where they unload (and the perishable nature). Not saying there couldn't be a manipulative reason too, but I wouldn't assume so by default.
