I’m not sure if you mean paper coupons or online coupons. But let me take each one in turn…

Let’s take paper coupons. Firstly, I’d say don't clip every coupon you see. Just because a coupon gives you money off an item doesn't mean you should use it. If it's not a product you would normally buy or are interested in trying, don't clip it.

It’s also good to consider combining coupons with sales for even bigger savings. Sure, it's great to save money on that full price pack of tortillas, but it's even better to buy the tortillas when it's on sale AND you can use the coupon. This might mean waiting until the price is right to make your purchase

Finally, you can often find better prices for shoppers who join a store's free customer loyalty program and use their card. Often a sale price doesn't apply unless you use this card.

When it comes to online coupons they work similarly to paper coupons. Instead of having a printed coupon to hand the retailer, you enter a code in a box during checkout online. It works just like a print coupon, helping you save money off your order.

There are many codes out there. Public online coupons are released to everyone, and they can be used an unlimited number of times. These codes are readily available on coupon sites all over the Internet.

Some retailers release private codes, which are given to only a certain group of people. They may be given to frequent shoppers or they may be given based on your past shopping history. These codes cannot be shared due to logistics. But these codes can be shared through a middle-man, such as a browser extension like shopper.com

The best way to save money online, though, is by using a web extension. This is because it can often be quite tiresome, and a hassle trying to search for coupons online. When you’re shopping online, the extension automatically sources coupons across the web and applies them to your shopping basket before checkout.
