I need a basic Add to Cart button that has a fixed price per item, but with the ability to add additional features for an additional fee. For example: Main product is $50.00. Add in extra feature #1 for $5.00. Add in extra feature #2 for $7.00. Total when added to paypal cart is $62.00.
I have already created all of the form items. I just need this last piece worked out.
