Packages are pre-bundled sets of products with a single retail price.
In the package part details page:
- Retail (List) price is the default price of the package that will appear in Point of Sale when it is sold.
- If a package is discounted and you want to show the savings on the receipt, you can utilize the On Sale function along with the Sale Price field. When a package is set to On Sale, the Sale price will be used in Point of Sale, and You Saved prints on the receipt.
- If you choose this option, you will set Retail (List) Price to match the calculated total extended price of all included items.
