1. When you're shopping online you have to be sure you are aware who you're buying from. If you're buying upon an online auction site, only buy from people that have positive feedback. On other sites look to see should they be a reputable company by trying to find reviews on them online.
2. Make it a habit to register for price alerts. It goes even for purchases that you've recently made. Price alerts will let you know whenever a product has dropped to some price you prefer. And if you've recently purchased at full price, you can ask for a price adjustment to satisfy the new deal.
3. When you shop online, be sure the site you might be on starts with "https". The "S" signifies that the site is secure, which entails that you can safely enter your personal information without having to be worried about identity theft. If a site lacks the "S" in it, you might like to avoid using it.
4. Do more research in the online store you are interested in before ordering a product from their website. If a store does not provide quality service or products, you will most likely find some negative reviews published on other sites. It is best to adhere to online stores with an excellent reputation.
5. When you enjoy the comfort of frequent online shopping, it's extremely important to keep changing the passwords you use for each and every account. Every few weeks roughly, make up a whole new password for your bank as well as the shopping sites directly. Use abstract words, combined with numbers and other odd characters for your strongest passwords.
