Online retailer Amazon offers thousands of vegan items and products that aren’t tested on animals as well as a huge selection of supplies for your animal companions.

But there’s an even better reason to use the site: helping animals while you shop, at no extra cost to you! Amazon will donate a percentage of the price of eligible purchases to PETA whenever you make them through AmazonSmile.

It’s as easy as set, swap, and shop.
Set: Go to Smile.Amazon.com and set “People for the Ethical Treatment of Animals” as your charity.
Swap: Before you start filling your cart, swap out the URLs (i.e., use Smile.Amazon.com instead of Amazon.com).
Shop: Start shopping, and voilà—Amazon will donate to PETA when you make your purchases.

You can even smile on the go: AmazonSmile has moved to mobile! You can now support PETA using the Amazon Shopping app on your iOS or Android device.
