Could someone please explain Fastenall Shipping

The only real drawback to Fastenal is that they ship at their convenience. The way it was described to me is when you drop your pallet off at a store, it is picked up by a truck going to the nearest distribution hub, if there is room on the truck. Once it gets there it sits there until they have a shipment to the hub that serves the destination, if there is room on the truck. Only then when a shipment is from that hub to the final destination (the Fastenal store) does the pallet move, if there is room on the truck. If your Fastenal is in Wherethehellarewe, AZ and sells one bolt a month, you may be waiting some time.
