adding a customizable charge to a configurable item

[lori_groff]

I have a configurable product set up. - customer will order by the inch.   I added a customizable option for a flat fee.   Magento is "adding the flat fee to the price per inch" instead of adding the flat fee to the "total" of the price per inch.    Is there a way to set this up?

Hi Lori,

It's an interesting question. 

It may be overkill for your use case, but I do know of a Magento Extension that will allow shoppers to enter a Quantity for the customizable option. That would potentially solve your issue. Shoppers could choose if they wanted 48 inches of the main product, but also wanted 4 of the Customizable Option item.

Best of luck!
