We have a client who makes custom keg covers, $79.99 each. He also offers 2 custom keg products, one you design the art $30, the other they design it for you $45, which is in addition to the $79.99 for the keg cover itself.
We want people to be able to purchase multiple custom keg covers at $79.99, but only be charged ONCE for the design option they chose [either $30 or $45].
Do you know of a way to do this with your plugin? We are DESPERATE for assistance! If you can email me at email@example.com or call me directly 602-538-4504?
