Hi Doug,

In the future, please post questions to the "Support Forum". The "How To" forum is supposed to be for instructional tutorial type posts.

As far as your question goes, you can add options to a specific product post, but not to the shopping cart contents page.

In each product post add/edit administration page, there is a section for options. With the product options, you can add to or subtract from the product base price.

Here's an example page if you want to see it in action:

Just click on the option dropdown boxes, and you'll see how it can alter the price.
