CartThrob Fees Version 1.2

CartThrob Fees addon enables your CartThrob powered site to capture fees. The fees can be tied to specific customer locations, item options, or custom data that's been set in your cart.

CartThrob Fees is an addon for CartThrob. Like other CartThrob addons, it must be uploaded and installed on your website, and CartThrob must be active for it to run. To use this addon, you will need to configure the settings, and it's advisable to add template tags to output fees information.

All fees are added to the cart as non-removable cart items. Like other items, they will be listed as order items in the customer cart history, and will be saved with other order items. Sample template code can be found here in the documentation.
