They've been dropping in price for a while at Costco. Look for a "*" or other symbol on the price card. The star means it's not going to be restocked. There's another character I can't recall to denote the item is on clearance. I'll bet this item has one of those two symbols by now.
I looked at these, but prefer my older boxes with a built in lock -- the hasp style isn't as convenient for me. COO Mexico, IIRC. I thought the Craftsman red wasn't quite the color I've been used to -- deeper, cooler red. Very good deal, I'll admit.
