I’d like to sell a product that includes an option that adds a one-time fee to the product but that one-time fee is not affected by the quantity selected.
So let’s say I’m selling a widget for $10 and want to include an instruction manual for an additional $5. If the user wants to buy to 4 widgets and the additional instructions, I’d like to charge them $45.
I’m struggling to accomplish this with Variant pricing as it wants to charge an additional $5 when the instructions for every widget is selected for every widget.
