Is there an easy way to modify a payment processor so that it only appears when the total cost of the order is between a minimum and maximum cost attributed to the processor?



e.g. to cover the following examples…



Don’t accept cheques for less than £5.00

Don’t accept Paypal for more than £1000

That function isn’t available, but it’s a darn good idea. I doubt it would be that difficult to code. Any coders want to take a shot at it?
