Just so. You really don’t want to be in that ‘pick ‘em off fromt he front porch’ situation. It’s a fantasy and you’ll probably get killed in the bargain.
We make a point of buying stuff in bulk some distance from where we live and we never give out phone numbers or addresses for ‘discount cards’ and the like.
We let our Costco cards lape a while back. Plenty of other places to do that kind of business. Oriental markets are good if you can find the right ones. Farmers markets, too. We live close enough to Montana to hit the Wheat Montana place for a big bulk buy. Cash only, of course.
Interesting point you made. Places like Costco can track what you’ve purchased It will likely become important once they start arresting hoarders.
