1. If you're considering buying a product online, check out the reviews. The reviews using their company people that have used the product will be able to give you a good idea about the product. You might be able to find out the caliber of the product, if it worked as described, and if you should make the purchase.
2. If you're making an online purchase, don't hesitate to contact customer support if you have a question. By contacting customer service prior to making your order, you'll find out how helpful customer care is and how quickly they respond. This is useful information to have when something goes wrong after you've made your purchase.
3. A reputable online seller should have a history that is recorded with the Better Business Bureau. Check with the BBB before you decide to part with your hard earned money to determine if there have been any major or continual complaints lodged against them. You don't want to be spending your money with a company that fails to provide.
4. Should you be shopping online, never give out your Social Security number. There is absolutely no website that really needs this number for you to make a purchase. If you are being asked for your Social Security number during checkout, perhaps you are on a scam website. Leave this site and find one that has a better reputation.
5. If a website is not secure, do not make a purchase. Simply look up at the website address when you are shopping. If you notice an "https" as opposed to an "http," you can feel confident enough to insert your credit card information. However, if there is no "s" inside the address, move on to a different site to be on the safe side.
