Creating a custom order total module.

[bcyde]

For the most part, what was suggested in the original post is *not* a wise practice. There may be a legitimate business need for it, but the approach sounds like it's a bit "off" from what would be considered typically acceptable practice.

If you're trying to add surcharges for customers using certain credit cards or planning to charge customers an amount different from what you're showing on your store and their receipts, you'll end up with chargebacks, a bad reputation, lost or dissatisfied customers, and probably get your merchant account frozen or canceled.

If you want to add surcharges, make them visible as another line item on your order and make sure the customer understands clearly why they're present and how to avoid them if they wish to not incur those charges.

Or build the fees into your product prices if that's possible.

There was a legitimate need for it in that the retailer we worked with partnered with a certain bank chain and offered a discount when using cards issued from that bank. They were not trying to add additional surcharges, what we did was create line items for the order that were clearly visible (as was the special discount offer throughout the site) via a custom order total module.
