Scenario. You do credit cards but for a $4 sale it just doesn't make sense so your minimum order for the cart is $12. You want the $4 though and you do a lot of cash sales at fairs or flea markets. If there was a checkbox for a discount code that would, when used, overlook the minimum order limit so the user can get to the pickup in store options or at least get to a cash payment option that would be awesome.
Or even just delay the minimum order limit until the payment portion. Maybe each payment option could have a minimum order limit. This I understand would have to come from the plugin designer.
Is there a way to do this already?
