1. When you are online shopping, make sure that you are just shopping on secure websites. Look in the web site URL plus it should display "https" rather than the usual "http" at the beginning. Usually have an up to date copy of anti-virus running on your computer too. This will make sure that you have a safe online shopping experience.
2. Do not spend too much money on shipping. Shipping charges can definitely add up. Many sites offer free shipping, free delivery once you spend a certain amount, or use a coupon code that allows you to get free shipping. Instead of paying your cash on shipping, look for a store that ships for free.
3. Ensure that you're entering your payment details on a secure site. Search for "https://" inside the URL of 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 wise idea not to trust those people along with your account information.
4. Read customer testimonials before you buy anything. People are delighted to complain about bad service online, so look for sites and testimonials which are terrible so you know what you're getting into. You should take bad reviews having a grain of salt, but if you see many, you know there exists a problem.
5. After you have found the items you want, check to see if there are any coupons offered. There are many websites that offer coupons. These coupons can be a certain percent off, a certain dollar amount off or free freight. Many times several coupons are available. If this is the situation, choose the one that will save you as much as possible.
