Hello,
I want to be able to create a product which has variable pricing depending on an option.
I want the customer to be able to create a book on the site, first choosing a binding, e.g. soft cover, hard cover etc and then choose the number of pages. The binding is going to be charged at a flat rate and then the customer is going to be charged x amount per page so for example of the customer chooses a soft cover with 55 pages it would be charged at £2.00 + (55 x £0.085)
My original thought was to build the binding and pages as a separate product and add them individually to the cart with the quantity being the number of pages, however if the customer wishes to order multiple copies I worry it might get a bit messy and confusing. I can edit the basket so it would look correct, however when it gets to the checkout, I havent found a way to edit this, so I feel it may get very confusing for the customer. Is there any way to add multiple of the same add on items to a product?
I’m not afraid to play around with the backend of the site, I just wanted to see of anyone has had any previous experience with something similar or has any other ideas 
Alex
