1. 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 see there's a pattern, hold off on buying anything until the upcoming sales period begins.
2. When you're shopping online you should be sure you know 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 when they are a reputable company by trying to find reviews to them online.
3. If you have questions while shopping, search for a live chat function in the online store. Many big brands (and even some boutique stores) now have this functionality. You are able to chat immediately with a customer care representative to repair any issues or answer any questions prior to buying. That can give you a lot of peace of mind.
4. Read customer testimonials before you buy anything. People are more than pleased to complain about bad service online, so look for sites and testimonials which are terrible so you know what you're getting into. You need to take bad reviews having a grain of salt, but if you see many, you know you will find a problem.
5. When searching out the best price to get a big ticket item, be sure to check the store reviews to see if other customers had a good knowledge of them. It is also a good idea to consult with the Better Business Bureau also. You want to make sure that the business is legitimate and values you as a client.
