1. When you're shopping online you need to be sure you are aware who you're buying from. If you're buying on an online auction site, only purchase from people that have positive feedback. On other sites look to see if they are a reputable company by searching for reviews upon them online.
2. Look for the right times to shop online. Often the stores that you frequent will have online sales that follow a time pattern. Many, for instance, schedule sales for the beginning of the month or at the end. If you notice there's a pattern, hold off on buying anything until the upcoming sales period begins.
3. When you are online shopping, make sure that you are only shopping on secure websites. Look in the web site URL and it should display "https" as opposed to the usual "http" at the beginning. Usually have an up-to-date copy of anti-virus running on your computer also. This will make sure that you have a safe online shopping experience.
4. Before buying from the new online retailer, do some research on them. Check online reviews from other customers to see the way it handles stuff like customer service, shipping, and its overall buying experience. You can also look into the BBB to determine if it has any disputes and whether those disputes were resolved professionally. Try contacting the company via email and phone number, if it's posted to ask questions on its business before you buy anything.
5. Speak with your friends with regards to their favorite online stores. There are millions of sites out there, and there is no method for you to find them all yourself. Talk to the people you know to find out who the reputable online retailers are, and where they like to purchase. This will save you a lot of time and energy.
