The order of the options does not matter. Using this method to add an optioned product will always result in the addition of a single new optioned product to the shopper's cart. The shopper can modify the quantity later in the checkout stage. Some options may require alternate pricing. For example, you may be selling items with optional copper, silver, or gold plating.
Silver plating doubles the price.
Gold plating triples it. To derive the final optioned price, all multipliers are added together and applied to the base price, then flat charges are added. They are added together, not multiplied. In addition to custom pricing, some options may add weight to a product. Weight modifiers are separated from the price modifier by a semicolon, as shown below.
