Trickls is a free browser extension that automatically turns online shopping habits into charitable donations - at no cost to the user. Whenever a user shops online, the extension will offer to add an affiliate tag to the purchase. Trickls then collects a fee from the retailer (they pay these fees anyways), and donates 90% of it to the charity of the user's choice! The user can login and track how much money they have redirected to charity without spending anything themselves!
