Auto-Apply Promo Codes with Honey (JoinHoney)

Honey is a browser extension and app that searches for coupon codes at checkout and can automatically try available promos for you, plus it tracks price history for some items. Install the extension, shop as normal and Honey will run through saved codes to see if any work, while the tool’s drop-down also links to offers and retailer pages. It’s a convenient, set-and-forget way to check for valid discounts before you finalise online purchases.
