Thanks for the heads-up and all the info above. I've been lucky so far. I shipped a kit out (one box) via USP a few months ago - no problems. I have a three piece shellpack packed and ready to go now.....55lb 25x25x25 box.....packed well....it's a 20" bass drum, 16 and 13 toms...hardware removed and packed in there separate.
I did a dry-run a few days ago...to get a price for shipping from here (Canada) to Florida. I can get insurance for loss but can't insure for damages because I packed it. Now I'm thinking of taking this package to UPS and let them package it when I'm read to ship it.
When I shipped the first kit a few months ago I asked for insurance....and paid for it....but didn't realize at the time I was only insuring for loss......NOT damages. I was lucky there was no damage at the other end.
