John Menard got his start selling closeout merchandise he bought for Penneys on the dollar. Their flash sales, both on the internet and in the paper flier often feature limited quantity deals, so finding something like this hammer isn’t a surprise.
I once bought some luxury vinyl floor tile, which was not bad and at a low price. I wanted one more box, and there were no more in the Menards system, so I called the number on the carton. The guy immediately recognized the SKU as a product he had clearances through Menards the year before. He didn’t have anymore, since the product was discontinued.and a one time deal at Menards.
His office was in Huntington Beach, likely a one man import operation working from his house.
