Is there a way to do a shipping rate that's a %?

Can I make a shipping rate that's a percentage of the total price of all the items being purchased?

For example:
Someone buys 2 items that are each $20, so they are spending $40 total on their order.
I want to apply 3% shipping to their purchase, so .03 * $40 = $1.20 shipping, meaning that the total amount of money they will be spending on their order is now $40 + $1.20 = $41.20.

Is this possible? If so, how do I do it?

Thanks in advance!

Hello Brandon,

EShop does not support the shipping plugin like this. Currently, it has Flat Shipping to allow you to enter a fixed cost for shipping. You can modify into this shipping plugin to have percentage of sub-total for shipping cost. If you know about PHP/Joomla, you can do that easily.

The file to modify is: components/com_eshop/plugins/shippings/eshop_flat.php

Hope that this will help.
Sincerely, Giang
