In order for any business to excel in marketing a product, they have to offer at least one of the following: a better product; the same product for less cost; or a product not available elsewhere. Often, it's difficult to meet one of these requirements without sacrificing another, i.e., quality vs cost, etc.
Most of the steel suppliers we work with are supplying similar quality. Our suppliers vary in terms of turnaround time, cost, and product availability. Midwest offers cost and product availability incentives. Onlinemetals offers turnaround time.
Online metals has six distribution centers located across the Country. They have to maintain inventory in all six locations, with separate warehouse operations and shipping departments. Their focus is on quick turnaround time, and that obviously involves costs passed on to their customers.
Midwest's focus is on a broad inventory and low prices. They achieve both by only having to maintain inventory in one location, and not having multiple warehouses and shipping departments to handle the workload. This cost, if you can call it that, is passed on to customers in the form of slow turnaround time.
Neither company is at fault. As customers, we must determine our needs, and place our orders accordingly.
