I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan

I always receive my shipments from Military Fasteners quickly without having to follow up and track down shipments. West Coast shipments arrive usually the next day via UPS ground, making it an effective choice. Thank you for excellent service.
