one idea for cheap shipping

It takes money to make money in a book publishing venture. Sometimes the
shipping costs alone are enough to really hurt. Here's one idea I've
come up with for packing boxes. Instead of the plastic bubble wrap, use
your shredder on the metric tons of print catalogs that come in.
Shredding can be cathartic and, once started, can feel almost like
pyromania! Take out your anger on the advertisers and put it to good use
for packing! I now have a big trash bag full of shredded paper for
shipping.
