Shipping costs are crazy these days. A lot of pangoers are great at re-using shipping materials, but no matter what there are still costs for packing items - tape, printer ink, packaging if you don't re-use, and the time it takes doing it. It would be nice to have the option to include a small fee on all orders that covers this cost. It should be shown as part of the total to the buyer before they click buy so they're aware as well.
