Have a math question-
I want to let customers upload blueprints for reprinting - I can add the upload part fine but want to be able to give a few size choices and ship to choices. I have to add shipping seperate since they may ship three sets to three different locations. I have priced by attributes now during testing and am open for suggestions-

1- File Upload - works

2- Sizes (radio check boxes)
18" x 24" (no extra cost)
24" x 36" ($1.77 extra)

3- Shipping (radio check boxes)
Ground ($9.00 1 time)
Overnight ($22.00 1 time)

I have the main product listed at 0 weight
