Harbor Freight stores get a limited number of blades. One customer can wipe out one weekly order. If you can, find the order person and ask how many they order, how often they order and when the shipment arrives each week.
My store got a dozen packages at first, but seems to be getting more now. I rarely go there because I cannot use the amount of blades I have on hand. It seems very few people in this area know about the blades. Currently I have 20+ packages of blades I am willing to share.
