DealDrop

DealDrop is a free Chrome extension that takes the hassle out of hunting for coupon codes. When you're checking out at a supported online store, it automatically tries to apply working promo codes so you don't have to dig through Google results or coupon aggregators. On top of that, it compares prices for the same product across different retailers, letting you know if you can get a better deal elsewhere. Just install it, shop normally, and DealDrop does the work in the background.

How does it work? The extension uses an algorithm that scans your shopping cart and matches it against its database of coupon codes and product prices for over 100,000 retailers worldwide. At checkout, it tries multiple codes and applies the one that saves you the most. The price comparison feature pops up when you're browsing a product, showing you the same item at other stores so you can decide where to buy. It also surfaces real-time price changes, which is handy for big-ticket purchases like electronics or appliances.

Who is DealDrop for? Anybody who shops online and wants to save time and money. It's especially useful for frequent shoppers — think students buying textbooks, parents stocking up on household items, or anyone making a large purchase like a laptop or furniture. Because it's a browser extension, there's nothing to learn: install, shop, and save. No login required, and it's free to use.
