That is a pretty good net price. The bars are cast ingots which (from memory, I'll check tonight with a tape measure) are about 4" wide, 2" thick and 30" long. They are divided into three or four pieces and would have to be cut in half at least to fit in the USPS $7.70 box.
More accurate details later tonight.--The ingots Evil Dog bought and split with me are 25" long by 2 1/2" wide by 1 1/2" thick and are divided into 4 sub-pieces, each between 6" and 6 1/2" long.
