Something that will scour the Internet for you, do all the hard work, and come back with the best way to save so you can cut down on costs just like you would in-store—only better and easier. My secret shopping weapon: Capital One Shopping You need to try it Capital One Shopping, formerly known to users as WikiBuy, is a free browser extension that searches the Internet for coupon codes when you're shopping online to help you get the best deal and save the most money. It also alerts you when items you've previously viewed go on sale, so you can take advantage of the better price. Here's how it works: All you have to do is click one button to install the browser extension for free. Then, next time you shop online, Capital One Shopping will automatically start browsing the Internet for the best price for you. By using this browser, I was able to earn 4% back in shopping rewards from stores like Macy's and managed to score my Echo Show 8 tablet from eBay for $81.43 instead of $115.49. Yes, it can save you that much. Not bad at all considering I didn't do any work except add the item to my cart. $94.84 saved? Not bad. And on top of all that, Capital One Shopping has pricing data available for so many retailers that you're more likely to find a better deal with them over other browser extensions. Some of these retailers include Amazon, CVS, Macy's, Target, Walgreens, and Walmart. The coupon for the best deal automatically applies at checkout, so you can focus on getting the goods while Capital One Shopping does all the work. It takes zero effort on your part—just one click—so trust Capital One Shopping next time you're ready to get a good deal.
