Online shopping through the Internet has become commonplace today, as it not only allows us to obtain the desired item without having to move from home, but it is also much cheaper in most cases. To save a good bit of money on our purchases on the Internet, we can make use of different extensions that are available for Google Chrome, the most used browser worldwide.
This popular browser has one of the most important add-on stores, placing itself ahead of other options such as Firefox or Edge. Its installation is extremely simple because we only have to access the Chrome Web Store with our Google browser and when we open them we can easily install it by simply clicking on the button in the upper right, called “Add to Chrome”.

So that we can save whenever we buy online, we are going to see different extensions that can help us buy cheaper or without having to compare prices by hand. We found add-ons for two of the most popular online stores, at least in Spain, such as Amazon and eBay.
We will also see extensions that offer price comparison services, so that we can always choose the cheapest option. In addition, they will be in charge of searching for valid discount codes to save even more, and others even offer a cashback service, which will allow us to obtain a refund on our purchases.

Amazon is considered the giant of online commerce worldwide, being one of the key websites when buying online. So much so, that it has exclusive plugins for Chrome.
