A GPO—or Group Purchasing Organization—is a cooperative buying program that leverages the collective purchasing power of its members to get group discounts from suppliers. Shelters United is the first and only GPO exclusively for nonprofit animal welfare organizations.

There is no cost to participate in Shelters United. If you are an animal welfare organization- no matter how large or small- you can join.

There is no minimum purchase required and no requirement to purchase specific brands! Most of the brands you purchase are discounted and with the help of our Shelters Specialists, you will be introduced to many products that may have even greater savings.

You will not be asked for a subscription or membership fee. All you need to do is complete the distributor application.

MWI carries all major manufacturer lines, so you can combine ordering to one place / one invoice. Shelters United is a great complement to other shelter programs. In fact, some shelter programs extend pricing to MWI. Please check with your manufacturer.

MWI is a $4B distributor of animal care products, with more than 50K products and 22 distribution facilities around the U.S. delivering next-day service nationwide. They offer an expansive manufacturer network- over 1K manufactures- to provide one-stop shopping for both large and small manufacturer lines.

MWI is committed to helping Shelters United members save money on the products needed to help homeless pets. MWI was so excited by what we are doing that they agreed to give us special shelter pricing that means great savings on many of the products you normally buy.

Because we have managed so many shelter programs in the past, it is very likely that you or someone with your group has participated in one of the programs we have been responsible for. Our team has brought you the Zoetis for Shelters program, worked with you on Merck Animal Health, most of the Purina pet welfare programs and many more.
