For an even wider selection of goods and services, shop through iGive.com. This is an innovative new service which has over nearly 700 participating merchants in all categories! Each merchant sends a portion of your purchase to the charity of your choice (make sure to choose Mighty Mutts!). Best of all, this portion of your purchase is tax-deductible, with iGive keeping track of your donations for you!
Make sure that you designate Mighty Mutts as your cause!
