What happens if you see a product with price X and by the time you checkout it has price Y? Can you claim somehow the previous price?

Same could happen with paper tags while they are in the process of updating them.

Best solution would be to have a transition period where for x hours it’s at the lower price in the system.

I imagine most stores would not change prices during business hours. For 24-hr stores, just do it at like 3am or something, those handful of customers won’t mind.
