We're packing removable mailing labels in our drift boxes since we are using 5 gallon buckets. It's easier to pick them off and put a new one on. It's also nice to show up at the PO organized. It takes a postal employee about 5 seconds to weigh your box and take your money if that is all you need to do. I guess you could get the label for the next town when you pickup your box... Kent.
