How do you use price extensions?

The price extension shows three things that can be ordered today, at the menu amount, not a “from” that does not exist later. It is not used if prices change every service and nobody updates them. Copy three current prices and the name as it appears on the menu. If they change tomorrow, they do not go on the extension. The ad states a menu at an old price. The person who calls argues at the door and the review says so. Three price lines linked to the menu or the listing, with the date they are checked. If the price is not stable, the extension comes off and the text remains.
