A lot of discussion about self-checkout fraud, but these tags are only for shoppers' convenience and don't control pricing - One tag goes in front of that SKU on display so you can see the price. At checkout, a barcode or plain old paper tag / printed barcode on the item itself gets scanned and that's where the price is looked up.

You've never been to a grocery store and had something incorrectly 'rung up'? It's happened to me more than a few times and I've never had a problem getting a "price check" and having the item adjusted according to the shelf label.

It's typically in-store policy.

Is Best Buy going to let you walk with a $10 Sony FX3 camera? Probably not. Are they going to fight you over a $10 difference in posted vs look up? Probably not.

From what I remember Connecticut laws used to require retailers to charge the lowest advertised and/or physically labeled price.
