Shopping is hard. You buy something and think you got an awesome deal on it, and then you find it cheaper somewhere else. Sometimes, you think you've done your research and you've found the best price, but you discover that it was cheaper just a month ago. With some patience, you could get that price again!

That's where the new Chrome extension called Slice Watch comes into play. Once installed, you can tag an item and add it to your shopping list, and it'll monitor popular shopping sites and let you know when the best deals come around on the thing you want.

When you're on a site supported by the extension (major retailers like Walmart, REI, Amazon, Best Buy, Target and Nordstrom are included), it'll turn teal. When you're shopping on a site that isn't, the icon is gray.

If you come across an item you want to buy, but not at the current price, just click the extension's icon, and click Yes on the window that pops out. It'll save your choice and alert you the next time the price drops. It doesn't get much easier than that!
