I have a Opencart store to sell my photographs and I offer different sizes of the same image for my customers to buy. I created a option called Print Sizes ( the bigger the Print Size the higher the item costs ) and the client selects the size they want before they can add to cart. What I would like to do is have a flat shipping rate based off of the Print Size they selected. Is there any way to have the flat shipping price reflect the iten size selected by the customer ?
The flat rate module that comes with Opencart does not have any options to do multi flat rate shipping base on item size and only does a blanket flat rate. I have in the past just used single flat rate that was somewhere in the middlle but for my customers that buy the small prints they are paying more than needed, and when a customer is buying a large print I have to pay the extra cost of shipping it which can get quite expensive when you are shipping a large stretched canvas.
Thank you for any help given.
