When shipping items from home or at a pack-and-ship store, what's the greenest thing to keep in mind? It's not the materials used to pack the goods, but how much they weigh. Choosing everything from the proper size box to the lightest bubble wrap can make a big difference in keeping costs down and fuel usage as low as possible. Oversized boxes and heavy paper filler can dramatically increase shipping costs and add to the amount of fuel used by planes and trucks to transport your goods. And remember to reuse boxes and packing material as an added way to go green.
