Now, when you shop on Amazon.Com, you can donate to the Mt. Diablo Amateur Radio Club – at no additional cost to you!

Instead of going to the normal Amazon.Com web site, go to a site called Amazon Smile. The actual address for us is:

When you do, Amazon will donate 0.5% of the price of your eligible purchases to MDARC. As Amazon explains, “When you shop at, you’ll find the exact same low prices, vast selection and convenient shopping experience as, with the added bonus that Amazon will donate a portion of the purchase price to your favorite charitable organization.” “You use the same account on and AmazonSmile. Your shopping cart, Wish List, wedding or baby registry, and other account settings are also the same.”

Your shopping experience is the same; you just start at a different web address. So please bookmark the address and start donating whenever you choose Amazon.

Checks & Cash

Of course, checks and cash are gratefully accepted. You may mail checks to the address on our Contact Us page. Please do not mail cash. You may also bring cash or checks to any Club meeting.


By the way, MDARC is a 501(c)(3) charity. Your contributions are as tax deductible as they are to other charities. If you need it, our IRS Employee Identification Number (EIN) is 23-7072059.
