The thin-inventory thing is getting excessive. The local CVS has been out of distilled water twice, and only had one pack of small paper cups. All those things have a very long shelf life; there's no need to maintain tight stock control.
Frozen corn, sure. Not corn on the cob.
I admit some bias, having started as a farm boy. But nothing is as horrifying as old corn on the cob.
(in the Midwest availability is pretty seasonal even)
regular industrial corn is livestock feed, corn-syrup base, plastics feedstock and the like. horrible stuff, grown in gargantuan quantities. you can't eat it without at least some amount of processing. it's just not food.
the stuff you eat off the cob is sweet corn. nobody grows, or eats enough sweet corn for there to be a glut of it.
Every single supermarket I went to was out of vanilla ice cream.
Holding inventory has an economic cost, even if the inventory has infinite shelf life — the money that bought or manufactured the inventory could be used elsewhere.
Sweet fresh corn on the cob is pretty perishable item. Worse than Apples at least.
