Is haggling an individualized price? What's stopping companies from allowing arbitrary bids on any item they can choose to reject? What if the future of the grocery store is eBay, a true nightmare.

I don't know why it is, because Americans are also pretty aggressive about certain topics. But confrontation, even low stakes like price haggling, is a problem.
