To make shipping worth it, you have two options, one, fill a gaylord to at least 60 inch and band the bottom and middle to protect it. For 40-50% that will get you to about 1200lbs. If you have the option, the best is baling it into a 60" bale, I buy it like that, and I am looking for bales to weigh 2200-2400lbs. I like low voltage/fire alarm/tele/ethernet wire to be by itself with no tinning and no attachments besides the plastic connectors. I pay a little bit more for that.

For THHN, gaylords work, same with romex. For 8s, 4ga, 2ga, MCM cutting it into 8-10 foot segments and putting that in a banded gaylord should get you to 2500lbs.

I got a few regulars here that do alot of wire, low grade mostly, and they ship very tall gaylords because the density isnt very high and one pallet space covers 2k lbs, usually the rate for single pallet shipping is the same at 800, 1200, 1500...up to about 2000.
