When you are shopping on Amazon, the impulse to buy with a single click can result in some bad deals. With the right websites and extensions, you can save yourself this hassle. And no, we don't mean old ones like CamelCamelCamel.

Of course, tools like CamelCamelCamel are still good at giving you a better shopping experience on Amazon. What we're dealing with here are better replacements for them or extensions that solve other problems.

The Review Index (Web, Chrome, Firefox): Graphical Summary of User Reviews

User reviews on Amazon are a mess, but they have valuable information about what you're purchasing. The Review Index tries to organize what people are saying by turning it into data.

The site analyzes all the user reviews for a certain product, ranking them based on certified purchases. It also runs a spam test to spot fake reviews and weed them out. Once it has all the information, it turns that into data about pros and cons. For example, with a laptop, you will find how positive or negative people have been about its screen, reliability, body, etc. The simple bar graphs make it much easier to figure out the popular opinion.

The Review Index works mainly with technology products like phones, televisions, headphones, routers, and so on. It's best if you use it for such gadgets.

The One (Chrome): YouTube Reviews, Final Pricing, and More [No Longer Available]

The One is trying to be the only shopping assistant app that Amazon users will need to install. It still has some way to go though, so for now, you'll need the other extensions we are talking about. That said, The One is worth a look already.

When you are looking at an item, The One simultaneously searches for reviews of that product from professionals on YouTube. The video is then embedded in the Amazon page you are looking at, so you never need to browse away. Just like that, you'll get to see actual unboxing and review videos.

The One also fixes a persistent Amazon annoyance. Anyone who shops on Amazon knows that the price displayed on the first page doesn't include add-ons like shipping and taxes. So The One displays the final, all-inclusive price for all sellers, even international ones that will ship to you.

Keepa (Web, Chrome, Firefox, Edge): Price Tracker With Messenger Bots

Keepa is still new in the world of price trackers for Amazon, but it has quickly built a base of people who swear by it. It takes some of the best features of existing price-watchers and adds plenty on top of it.

Keepa has bots for both Facebook Messenger and Telegram, which you can use to quickly search for a product's price, and set up price alerts. Since most of these trackers work through desktop browser extensions, this is a nice touch that brings the tracker's features to your mobile.

As for the features, they are what you would expect from any good tracker. You can add products to a wishlist, as well as set a price alert. You will see the price history of any product you are looking at on Amazon.

There's also a Deals section, but I didn't find anything worthwhile there. There are better ways to get the best discounted deals on Amazon.

Recon Bob (Chrome): Can You Trust That Seller?

Usually, you purchase items directly from Amazon, but there are times when a product is much cheaper through one of Amazon's third-party sellers. But how can you tell if the seller is trustworthy? Recon Bob can figure that out for you.

Before you confirm the purchase, check the seller's rating on Recon Bob. The tool will analyze what other users have said about that seller, warning you about any potential issues. Even if the seller has majorly positive reviews from customers, Recon Bob will still flag the problem posts to tell you what can go wrong.

Remember, even though Recon Bob is only available for Chrome, you can install Chrome extensions on other browsers.

Needzly OneSearch [Broken URL Removed] (Web): Search Amazon, eBay, and Walmart (and See All Deals)

You would prefer Amazon on most days, but if the product is cheaper on eBay or Walmart, you might as well pick it up there, right? Needzly has introduced a universal search engine for all three online retailers.

Search for anything and you get a list of prices from cheapest to costliest. The search, unfortunately, doesn't include shipping costs, so even when you see something cheaper, remember that it might cost more with shipping. That said, you can still save a big chunk of money by cross-referencing your item with eBay and Walmart before you buy it on Amazon.

Needzly [Broken URL Removed] also has a deals page where it finds discounts across all three stores. These are usually the cheap items like what you'd find on the Amazon's daily deals, but hey, who said those aren't worth it?

What Amazon Hides

These new extensions and websites will naturally help you save money. But what you probably don't know is that Amazon doesn't easily disclose some of its best deals and discounts. Here's how to find what Amazon hides.
