I have products where customers can select to make desing by compagny.
The price of the design is fixed $50 for the design.
When I add a costumizable Option and they select "make design" + $50
this is okay if they order only one product. Price product $22 + $50(option) = $77
If they order 4 products this is $200 added < is not correct.
$22 + $50(option) = $77 * 4 = $308
I want the option only to be added ones per product.
$22 * 4 = $88 + $50(design option) = $138 instead of $308
is this possible?
