Sumas WA Post Office-Close to a Copper Buyer

I was in the Sumas WA post office receiving Canadian coin and the clerk remarked on how heavy the box was. I was ripping into it on the counter because I don't want to take a sealed box across the border so I said it's coin. She tells me a local (ie not Canadian) gets flat rate boxes of pennies weighing just about 70 lbs. So is this person a forum member?
She also said that people get heavy boxes of lead shot and of empty/used shotgun shells for the brass content??? Comments
