1. Be sure that you're entering your payment details on a secure site. Try to find "https://" in 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 wise idea not to trust those people along with your account information.
2. If you like a web-based store, sign up for their email distribution list. You will probably receive some coupons and information about deals inside your mailbox. Check these emails regularly to keep up to date with discounted prices and promotional offers. Most online stores often offer free freight or discounts on certain products.
3. Get engaged in the social media of the favorite online retailers. Brands with big online presences typically put plenty of cash behind their social media, and that includes offering their followers some mega-discounts and exclusive deals. You can be one of the lucky ones scoring these handles just a quick follow or fanning.
4. When shopping online, be sure the site you are on starts with "https". The "S" signifies that the site is secure, which entails that you could safely enter your personal information without having to be worried about identity theft. In case a site lacks the "S" in it, you might want to avoid using it.
5. If you want to buy books online, you'll get a better deal if you get them used. Depending on the condition you obtain them in, you may just end up paying a few cents plus shipping. Make sure you read the description of the book to see if you can find any damages you should be aware of.
