Powder River Office Supply is a locally owned family operated business in Gillette, Wyoming, founded in 1978 by Herb and Dorothy Carter.   

With a vision and passion for office supplies, the Carters have offered and supplied quality products, competitive prices and professional and courteous service for 35 years.   

But don't let this simple approach fool you. Powder River Office Supply can do things that most big box stores and mail order catalogs can't. Free Delivery. Free Shipping. Overnight Service. How many businesses can guarantee this kind of service, and not make you pay the extra dollar for it? Not many these days.

Not only has Powder River been serving Northeast Wyoming for all these years, but recently they have branched out. We deliver weekly to Moorcroft and Sundance. Let us know if we can save you a trip. Having access to over 40 warehouses nationwide has enabled us to speed up delivery time and eliminate delivery costs for our customers.


We are still celebrating years

of great customer service

We are dedicated to providing our customers with a quick, efficient, hassle-free shopping experience. This "mom and pop" practice is easily noticed when you ask for your order by ten the next morning, and you receive it, personally hand-delivered with a bag of candy! Or, you are greeted by name as you walk in our front door. This is a welcomed contrast in a world of do it yourself, find it yourself retail environment.
