Add product to bundle as extra

Hi there,

I have a bundle with 3 products which take the primary product price of 50 EUR. The users cannot select which products – it is a set bundle at a set price.

I want to however offer an additional optional product to the bundle (a gift wrapping service) which costs an extra 5 EUR. If you select it, then you are charged an extra 5 EUR on top of the bundle price. Is that possible at all?

Many thanks.

PS very nicely designed plugin, clean and exactly how it should be.
