1. Read customer testimonials before you buy anything. People are delighted to complain about bad service online, so try to find sites and testimonials that are terrible so that you know what you're getting into. You should take bad reviews with a grain of salt, but if you see many, you know you will find a problem.
2. Many online shopping sites offer discounts if you use a "coupon code". These codes can be found online by entering the words "coupon code" along with the manufacturer or name of the website you will be buying from. They might offer a percentage off or free shipping by simply entering within a simple code which can be easily found by investing a few minutes looking for it.
3. If a company has a newsletter, sign-up. Often, companies will give sneak peeks, special deals and coupon codes to people on their own mailing list. However, be careful. You don't want to sign up for every company's newsletter or you'll soon be buried under endless emails. Only join a company's newsletter if you really like their products and would use a discount code.
4. Make sure to read all the information about any product you are considering purchasing. Just looking at a picture online can be deceiving sometimes. It will make a product look bigger or smaller than. Make sure to look at the description so that you know exactly what you really are purchasing.
5. Make it a habit to register for price alerts. This goes for purchases that you've recently made. Price alerts will let you know when a product has dropped to a price you like. And if you've recently purchased at full price, you can request a price adjustment to meet the newest deal.
