Shipping 80lb amps.

You can usually find pallets in industrial parks or behind active strip malls. 

You can screw down the crate onto the pallet but you also need to use straps. Ratchet types work well but make sure to go in opposite directions. 4 straps.

 It can still be turned sideways to fill in gaps and other items will be stacked on top of it regardless of stickers. Also insurance does work in case item goes "missing". 

One more thing labels on wood can be problematic. Multiple locations on the outside, label on the inside,  maybe one of those tracking devices folks on using onchecked luggage. Good luck.

I have shipped quite a few items that were expensive/heavy. I would and have simply build a tight fitting plywood box to encase the item. Overkill? No frikken way

@skids   this is how I ships things.  Overkill?  No frikken way. 🤣

The UPS driver commented when he picked up a box of a pair of electrostatic speakers from my house  "This is a big box, big boxes don't do well, I hope it makes it".  WELL, it didn't make it.  All the above comments apply to this case.  I never got reimbursed.  They said I didn't take out the insurance.  (I have always taken out insurance)

SO, build a wooden box around the outside cardboard box OR plan a vacation to deliver or pick up the item.  Yes, more time consuming and more money but it beats having your property destroyed.

Bigtwin,

Exactly.
