We have shipping rates set up based on product weight (and 5 different shipping Zones).

Our customers have 2 payment module choices (money order and cod), and because of the extra fees we get charged for using cod we'd like to only allow it for shipments over a certain weight.

THis might not make complete sense, but there are more boring details about Norwegian Postal Services I don't really want to go into right now...


The gist of what we want is:

Over 500 grams total weight = choice of 2 payment methods
Under 500 grams total weight = only one payment method allowed (money order).

Is this possible?
