This is a key step! If you don't do this, Hub Area Habitat will not receive the donation. Click the Designate Your Gift button. The following image will appear.

Either enter 57402 as the zip code, Hub Area HFH for the affiliate, or South Dakota for the state. Depending on what was entered, one or more affiliates will appear. Select Hub Area and finish the designation. Continue to fill out the first form. When done, click the button 'Click to proceed.' Complete the credit card information and submit your gift.
