You need to watch (with a 47Lb WOPL 700), that the weight stays under 70LBS or your shipment will go Freight. a double boxed, and half a roll of SMALL PINK BUBBLEWRAP, will keep your amp shipment under that weight and total for the 2 boxes would be $7.00 and $24 for Bubbles and tape...... I could ship a shitload of amps for the price of a $400 Cabbage Case (Which doesn't even include the $100 to get it halfway across the US). If you are having one built or maybe three amps built, the Cabbage Case is a waste of money. If you build and ship amps all the time, it's still a waste (IMHO). At $30 in shipping supplies, You'd need to ship at least a dozen amps to pay off that case or more (I get 2 amps out of 1 roll of bubbles)..
