option price in combination with degressive prices

Hi,

There is no option to do that. Now technically, with customization you can do pretty much whatever you want. HikaShop has triggers for add to cart events, so you can catch them in javascript to display a popup with what you want in it and when the customer validates the popup, catch the request with a system plugin which would save the option to the cart, etc. However, all that will require a JS/PHP developer to work on that.

The main issue in your case is that the "price with options" is calculated based on the unit price for a quantity of 1 and since you don't have that price, it can't calculate anything and display 0 instead. So a simpler solution would be implementing the quantity.checked javascript event of HikaShop so that when the quantity is selected the "price with options" is updated and the price of the option is updated too. And you could also do that when the page is being loaded. That would be way easier than the solution with the popup and it would be less steps for the customers too. However, it would still require a javascript developer to work on that for you.
