Ha ha. Yes, I did a trade with a guy in California who paid me with 50 pounds of wheel weight ingots in a $10 flat rate box. The wee lady mail carrier was not happy. "If it fits, it ships."
Buying ww's in ingot form saves the hassle of melting "raw" ones but is more expensive. Plus one doesn't know for certain that ww's is what you're getting. (Checking the mystery alloy with a brinnell hardness tester will at least tell you if it's in the proper hardness range for ww's which 8 out of 10 times is close enough.)
