I’d like to be able to use an absolute cost for a product in the Product > Option > Variant instead of only having the + or - modifiers. I’d like to see a box added for price where I can enter a direct price for the variant. I have put this on the wishlist:

Greetings,
Seems like our price margin cs cart addon might work for you. Addon is close to beta version. It will be great if we can work together and shape it up for you. Please contact our sales department if interested, I am sure we can find a good solution for your problem with our addon 
I would be interested in this addon
