If I know that the guy who came to the same supermarket as me got his water cheaper just because he got there ten minutes earlier, how much do you think I feel like shopping at that place?
what about the price changing once you've picked up the item?
I'd honestly consider endorsing a law that says pricing can not automatically change more than X/day.
I think a rule which says that once a price changes, the POS system must universally use the lower price for the next two hours (for the largest supermarkets, maybe 1 hour for a mid-sized, and 30m for a small metro sized shop) would be appropriate.
So, if a price increases itβs very unlikely a customer who has seen the lower price will be charged it, and if a price lowers, it must be implemented instantly.
