I'd like to buy an EM and have it shipped by NAVL. Any advice on how to prep it? I've only used NAVL twice before. Shipping worked okay, but they prepped those games with cardboard and blankets, and they folded down the backbox. The backbox on an EM comes off completely. Does anyone have any experience doing this? I suspect they would cardboard and wrap the body, but I don't know what they'd do with the backbox. I'd like to see both arrive with no damage. Should I ask the seller to do any specific prep? Thanks for any advice.
