1. Make sure that you're entering your payment details on a good site. Search for "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 good idea not to trust those people along with your account information.
2. Find out the online store's return policy. In case you are considering making a purchase on an item that you might like to return, be sure you find out if returning the item is definitely an option. Sometimes when you shop online, items cannot be returned and you do not want to be saddled with an unwanted item.
3. If you like an internet store, join their email distribution list. You will probably receive some coupons and information about deals inside your mailbox. Check these emails regularly to remain up to date with discounted prices and promotional offers. Most online stores often offer free shipping or discounts on certain products.
4. When you are searching for a spot to buy a product and no results seem to be from familiar retailers, you should be hesitant about entering your information. Look for security signs from Verisign or Cybertrust, so you know the retailer is not in the market to take your hard earned money.
5. Before going shopping at any online retailer, do a quick search for promotional codes. Most of the big retailers often have promotions running that are not advertised on their home page. Carrying out a quick look for these codes will allow you to insert the code at checkout to save money.
