Adding product with quantity to cart total automatically based on cart variant

[senorpuck]

I am building a t-shirt printing site that that offer multiple colors and discounts on quantities. Printing for the logo is charged based on the amount of colors in the logo. This is setup as a cart variant at the moment. This price is then added onto the individual item.

The artwork for the logo is charged at a fixed rate per color per order. This is $20 for 1 color, $40 for 2 colors etc. I am looking to added this into the cart based on the selection that for the cart variant when selecting the amount of logo colors, but I am unable to find a way to do this. I looked at adding a calculation rule but this only allowed me to add one price and didn't take the quantity into account.

e.g.

Base price: $10
Color x 1 per shirt: $5
Shirts x 10: €150
Artwork cost per color: $20
Total: $170

I hope that's clear enough

I have been looking for through the forums and I haven't been able to find a solutions. I hope someone can help me out

Have you tried this or written to the developer?

Thanks for your response.

I looked at the demo online but I wasn't sure if it would what I needed. Do you think it does?

Ok - I don't use it just because I don't need it but the best idea is write to the developer -

I can say that quite a few use thsi product and has been around a for a while - so just give them a try.
