Share Your Shipping Secrets/Tricks Here

Have you ever had to file a claim? I've read they won't fulfill a claim if the shipping company didn't package it, but luckily, I've never had to go through that process.

Not yet. The USPS has some really unrealistic guidelines for their flat rate boxes. For instance, whatever you're sending must be 3" away from every side of the box inside to allow for packing. That's ridiculous. It's simply another way for someone to get out of something. I still insure it nonetheless.
