To ring in a special it will no longer be a regular button, your buttons will stay their consistent prices, this is because togo orders are not valid for specials and must be rung at normal price. Specials are also only valid with a purchase of a drink. So if your customer doesn't purchase a drink then they don't get the food special and must be rang at regular price.
For the time being we are no longer doing happy hour. We may decide to bring it back in the future.
