1. Look for the right times to shop online. Often the stores that you frequent will have online sales that follow a time pattern. Many, for instance, schedule sales for the beginning of the month or at the end. If you see there's a pattern, hold off on buying anything until the upcoming sales period begins.
2. Be sure that you're entering your payment details on a secure site. Look for "https://" inside the URL from the site that you're seeking to buy something from. If you don't see that or no symbol of any website security, then it's probably a great idea not to trust those people together with your account information.
3. For those who have questions while shopping, look for a live chat function in the online store. Many big brands (and even some boutique stores) now have this functionality. You are able to chat immediately with a customer service representative to correct any issues or answer any questions prior to buying. That can give you a lot of reassurance.
4. To help protect your credit, use only one credit card for online purchases. This will help you quickly track your spending habits when the credit card statement comes in the mail. If you notice any charges which you did not make, call the credit card company immediately and report it to them.
5. Sign up for your favorite online stores' newsletters. Many times online stores will be sending out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to save money, you could possibly score some terrific deals on items you were going to purchase anyway.
