Please open below link and check "Interested in Embroidery" checkbox.


Some options will show which are product custom options. Here, two options have price "Logo Creation Fee" and "Embroidery Logo Charge". When I select all options and add to cart. On cart page, If I increase product quantity, all option's price increase with quantity. But I want that when product quantity increase, only "Embroidery Logo Charge ($35)" custom option is vary with quantity not "Logo Creation Fee($300)".

Example : If product price is $50 and product have two custom options like- "Logo Creation Fee ($300)" and "Embroidery Logo Charge($35)". When we add product(quantity 1) in cart with both custom options (subtotal is $385).

Subtotal is: (product price ($50) + Logo Creation Fee ($300) + Embroidery Logo Charge($35)) * 1 = $385

Now, we increase product quantity (2) then subtotal is :

Subtotal is: (product price ($50) + Logo Creation Fee ($300) + Embroidery Logo Charge($35)) * 2 = $770

But I want to change in subtotal. I want subtotal like this :

Subtotal is: ((product price ($50) + Embroidery Logo Charge($35)) * 2) + Logo Creation Fee ($300) = $470 ($170 + $300)

"Logo Creation Fee ($300)" not vary with quantity, add only one quantity for one product.

Means Product's "Unit Price" display without custom option's price.
