Hello All,
I have a problem, i’m adding a new product Lighters. But we sell them printed.
If a customer pick lets say 500 lighters it does 500x the price. But when i add a option say printed with one color. One color cost 39,- two colors cost 49. When i pick one color then it does 500x 39,- also 
But it needs to just add the 39,- to the total of 500 x the price.
Hope someone can help me with this.
