You can obtain large cartons from Walmart on the overnight shift. Also Home Depot and
Lowes, though Lowes insist on being homos lately. You can get soft (and hard) foam slabs
from the dumpsters behind large craft stores (Michaels), Pier 1 Imports, Staples (for
those that still have conventional dumpsters). Sometimes cardboard is a better choice for
cushioning material, use your judgment, and it adds weight.
Avoid UPS. Fedex and USPS are much cheaper. But if you use Fedex you need to consider
*ALL* the excessive G-forces your items will be subject to. For heavy and/or bulky items I
wrap wrap wrap the box with cheapo packing tape, dollar store or Wally World, 1$ a roll.
It just makes much more sense then spending 2.50-3.50$ a roll.
