Amazon has a program called AmazonSmile, which will automatically donate 0.5% of your purchases to the charity you select. It costs you (and the charitable organizations) nothing, and it's just like shopping on Amazon normally, but you get to do a world of good.
When you click on the link below, you can choose the Lighthouse Rescue Mission as your charity, and from then on, a portion of most purchases you make on Amazon will benefit the Tulare Lighthouse Rescue Mission.
Items that are eligible for the donations will be marked as such on their product pages. Unfortunately, Subscribe-and-Save purchases and renewals don't count.
