NPR's Planet Money looked at a grocery store in Norway. They had a reporter sitting in the store's HQ, and they had received a secret shopper report that a particular product (can of mushrooms in water) was 0.20 Kroner less at a competitor. The reporter watched the price get updated in the chain's central database, then ran down to the store that was below the HQ and saw the shelf tag change about 9 minutes later.

That particular store has a policy of not increasing prices while the store was open, they could only lower them.
Stores will have to set good policies and follow them. Stores open 24/7 will probably have to have set times to raise prices.
