1. Be wary of any emails you receive, even if they appear to be coming from a retailer you trust. Never click on a link that directs you to a web site other than usually the one you shopped on. Should you do, you may become vulnerable to a gimmick. Rather than simply clicking on an email hyperlink, just go as much as your browser and type in the web site you would like to go to. It really is much safer that way.
2. If you are going to be online shopping, make sure that you do it from a computer connection you know is secure, like one that you have in the home. Hackers try to find WI-Fi connections in public places if they are scouting for victims, so avoid shopping when using them.
3. If you're considering buying a product online, browse the reviews. The reviews off their people that have used the product should be able to give you a good idea about the product. You might be able to find out the caliber of the product, if this worked as described, and if you should make the purchase.
4. Sign up for your preferred online stores' newsletters. Often online stores will send out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to spend less, you might be able to score some terrific deals on items you were going to purchase anyway.
5. For those who have questions while shopping, search for a live chat function on the online store. Many big brands (and even some boutique stores) now have this functionality. It is possible to chat immediately with a customer service representative to correct any issues or answer any questions prior to buying. That can present you with a lot of peace of mind.
