Hi Darryl,
I don't know how others are doing it, but I use a listener for the
payment_methods_query signal to conditionally reduce payment choices
like this:
def adjust_payment_choices(sender, contact, methods, **kwargs):
if should_reduce: # whatever your condition is
for method in methods:
if method[0] == 'PAYMENT_PMTKEY':
methods.remove(method)
It would be nice if methods were a dict rather than a list of tuples.
