I've never received an incorrect order from ACS, even when dealing with small hardware such as nuts, washers, screws, etc. Shipment is always fast and with reasonable shipment prices for my needs. Even my smallest of orders is processed and ship quickly. I'm a long-time ACS customer and I expect I will be for a long time.
