1. When you're shopping online you should be sure that you know who you're buying from. If you're buying with an online auction site, only order from people that have positive feedback. On other sites look to see if they are a reputable company by searching for reviews to them online.
2. Turn it into a habit to sign up for price alerts. This goes even for purchases that you've recently made. Price alerts will let you know whenever a product has dropped to a price you like. And if you've recently purchased at full price, you are able to ask for a price adjustment to fulfill the new deal.
3. When shopping online, make sure the site you happen to be on begins with "https". The "S" means that the site is secure, which entails that you could safely enter your personal information without having to concern yourself with identity theft. If a site lacks the "S" in it, you might want to avoid using it.
4. Although it might appear tedious, make sure you read the contract and terms before you purchase with a website. These documents have valuable information on what you can and cannot do when you have an issue with the item that you bought. Read them thoroughly in order that you do not have an unwelcome surprise when trying to come back items.
