If I've understood your question correctly, you need to edit the price of an existing configurable product.

You're going to need to change the price in two places (I think).

First off, when you create a configurable product with 'associated products' each associated product is a simple product in itself. You should search for the refill product and edit the price in there as you would any other product. Then you will need to edit your configurable product, navigate to the associated products tab and edit the difference in price there (so $-14.00).

Should do it.

EDIT: This is the section you want. It's in the associated products tab of your configurable product and allows you set price differences for each product.
