Hi Jerome,
I apologize if I was not clear enough in my description. So on the screenshot you can see, that the user placed in the cart 1 All-natural bath bomb ($6) and 1 Organic lotion bar ($5) - White Container - THAT'S THE PROBLEM ITEM. So 6+5=11, but the total in the cart is 16. It happens, because the Organic lip balm has a Characteristic (White Container), so the price for it doubled. (additional $5). So the total price is $16 (6+5+5), but should be 11.
Please let me know what additional information I can provide to help clarify it.
Thank you
Tatiana
