1. Be wary for any emails you get, even if they appear to be from the retailer you trust. Never click on a web link that directs you to a website other than the main one you shopped on. If you do, you may become vulnerable to a scam. Rather than simply clicking 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. Do not forget to comparison shop when you are looking for things online. People usually do that when shopping in physical stores, but they don't think about it on the Internet. If you choose the first sale you see, you will find a chance you may miss out on a much better deal elsewhere.
3. If you're purchasing clothes or shoes online, be careful with the sizing. Some items typically run smaller or greater than normal. Some shopping sites will advertise if an item runs true to size. If the site doesn't list anything about sizing, glance at the reviews. In most cases, if an item is running larger or smaller, the reviewers will let you know.
4. Once you enjoy the ease of frequent shopping online, it's very important to keep changing the passwords you use for each account. Every couple of weeks roughly, make up a whole new password for the bank and also the shopping sites directly. Use abstract words, combined with numbers and other odd characters for the strongest passwords.
5. If a website is not secure, do not buy something. Simply look up at the web address when you are shopping. If you notice an "https" rather than an "http," you can feel confident enough to insert your credit card information. However, if there is no "s" inside the address, start working on a different site to be around the safe side.
