1. In case a company has a newsletter, sign-up. Often, companies will give sneak peeks, deals and online coupons to people on their mailing list. However, be careful. You don't want to sign up for every company's newsletter or you'll soon be buried under endless emails. Only sign up for a company's newsletter should you really like their products and services and would use a discount code.
2. When shopping online, always try to keep in mind the cost of shipping. Many sites offer free shipping on purchases over a certain amount. In the event that you do have to pay shipping, make sure that it is going to match your budget after you've added everything in your cart. Possessing a full cart only to find out you are unable to afford the shipping is never an enjoyable experience.
3. When you are searching for a spot to buy a specific thing and none of the results seem to be from familiar retailers, you should be hesitant about entering your data. Look for security signs from Verisign or Cybertrust, so that you know the retailer is not in the market to take your hard earned money.
4. Make sure that you're entering your payment details on a secure site. Try to find "https://" in the URL in the site that you're attempting to buy something from. If you don't see that or no indication of any website security, then it's probably a wise idea not to trust those people along with your account information.
5. Make sure to read all the information about any product you are considering purchasing. Just looking with a picture online can be deceiving sometimes. It will make a product look bigger or smaller than it is. Make sure to read the description so you know exactly what you are actually purchasing.
