I have customised the ZenCart purchase process to some level and have a file field in the attribute section that takes a logo for customers to have printed on their products.

At the moment, I have filled the 'Onetime' with 25, to charge the customer £25 per product, no matter how many they buy.

Now this needs changing slightly. I need to charge the customer jsut £25 PER TRANSACTION not PER PRODUCT.

Any ideas how to do this?

Thank in advance guys!
