1. If you find a great product on your own favorite site, search for it in a search engine before you buy it. Make note of the model number or brand, and do a quick search to make sure you can't obtain it cheaper from somewhere else. You might be able to save a few dollars this way.
2. Should you be shopping online, never give out your Social Security number. There is not any website that requires this number for you to make a purchase. If you are being asked for your Social Security number during checkout, you may be on a scam website. Leave this site and discover one which has a better reputation.
3. Sign-up for any identity theft protection your credit card company offers, especially if you shop online often. No matter how safe you are or how diligently you believe you are able to protect your details, it's never one hundred percent guaranteed. Take full advantage of automatic ID protection and know you will have back-up, should the worst occur.
4. Transform it into a habit to register for price alerts. This goes even for purchases that you've recently made. Price alerts will let you know each time a product has dropped to a price you like. And if you've recently purchased at full price, you are able to ask for a price adjustment to satisfy the new deal.
5. Make sure that you're entering your payment details on a good site. Look for "https://" within the URL from the site that you're trying to buy something from. If you don't see that or no sign of any website security, then it's probably a great idea not to trust those people together with your account information.
