It’s easy to overspend when you shop online. 

You buy things with the click of a button, no cash exchanging hands. You can shop in your pajamas at 2 a.m. And once you’ve made your purchase, you see targeted ads everywhere, enticing you to buy more.

But if you can fight the temptation to impulse buy, online shopping can help you find the best deals — especially when you download Google Chrome shopping extensions.

Forget searching for coupons and promo codes or browsing a handful of sites to compare prices. These money-saving Chrome extensions do that work for you. Try one or two from this list to save money during your next e-commerce binge.
