Does anyone know of any ways (tricks?) to use the flat rate envelopes or flat rate shipping if they order only one or two items? My problem is adding it and then if they order more than 2 (which wouldn't then fit into a flat rate box anymore), and if they pick that option, I have a problem. I have my doubt whether this can be used in the module but, just hoping that (maybe) someone has figured out a way to do it.
