What if I told you that you could purchase the common wares you use with a 20-50% discount in the same shops you go to without actually doing anything?

What I am talking about are coupons. Figuratively speaking, yes, you do have to do something. That is log in to your PC and browse some sites. But that's it. No pesky promos, reposts or likes. Pure discount offers from respectable shops.

Traditional paper coupons are usually found in papers, magazines and so on but nowadays, in the digital era, it is much more efficient to find them online and either save the image to your phone or print them out. 

Another issue is that there are literally thousands of shops with their own sites and leafing through them will take up all your spare time. However, there is a solution to that. When demand appears, offer follows. There are a lot of easy-to-use, user-friendly websites who host coupons and other offers. They have filters, ratings, categories, and tags to efficiently show you just the things you need. Let's look at some of the major coupon sites.

Groupon is extremely popular with different services. You will find holiday, travel, beauty, restaurant, activity and other offers that provide some kind of service. 

This site is perfect for people who look for new impressions. If you want to try out horse-riding or surfing at a lower cost, then, go to Groupon and purchase the coupon. A lot of companies can provide virtually free services for a client that comes first time to them. And here is another difference that the Groupon offers. You have to pay for the coupon. But you don't actually pay for the coupon. You pay for the discounted service. Having bought one, you just print it out and get the service without any more charge.

CouponBirds is a really User-Friendly website. Its emblem reminds twitter but they are nothing alike. When you come to the site you can see offers of the day. So, no need to look anywhere if you don't have much time. Apart from that, there is a number of categories, by brand searches and exclusive offers, not to forget free shipping options. One other thing I like about CouponBirds is the minimum amount of advertising. Despite that and a friendly interface, the site gets millions of views daily.

Now, this large player isn't strictly speaking a coupon site but it will save you money shopping online nonetheless. What it offers is cashback. It means you will get some money off every purchase in the shops that have affiliate programs with this site. And it has a large number of partners such as Amazon, North Face, Walmart, Kohl's, Zara, H&M and many others. 

One of the advantages of this service is that you don't actually have to use the interface of the Ebates site. You just log in and keep the tab open while shopping through different shops. When you purchase something, you get your money back automatically. The usual percentage of cashback is around 3-4%, however, some special offers may get you as much as 40% of the total cost back.

Oh, and by the way, they offer money for promoters. If you manage to call people to Ebates with your link you will receive 10$ in gift cards.

Coupons. com is a traditional site, first among such services to offer discounts and coupons. They've started out when coupons were printed and you had to clip them. Nowadays, it is a major online business with hundreds of thousands of clients and partners. But their sales model hasn't changed. However, instead of purchasing coupon booklets, you can look them up online and print them yourself afterward. 

What really makes coupons.com shine is its outstanding ease of coupon search. You can insert your ZIP code to find some local shops or simply look by brand or category. Whatever you are looking for, you are going to find it very soon and more besides since the site has nice recommendations. 

RetailMeNot is another one of the oldest coupon sites. Right now its audience is comparable to the Coupons.com and it has partnership contracts with hundreds of thousands of companies. It started its path in 2006 as a small company and is now one of the leading American sites. The main advantage of RetailMeNot to me is that it has a very convenient app. You can switch on the geolocation so it will establish what kind of offers are available close by and will notify you of them. In addition to that, you can keep the coupons in the app and so there is no need to actually print them out, which I find convenient as well. 

There are tens of similar websites with similar offers and different perks. The use of one or the other depends on your preferences.
