1. When you are creating any purchases online and you are required to produce a user account, never utilize the same passwords that you use on other websites. Do not use your e-mail or banking password to make your account to buy shoes from a web retailer. If a person was able to check this out password, they might have access to not only your profile on the retailer's store.
2. When you are searching for a place to buy a specific thing and not one of the results are most often from familiar retailers, you should be hesitant about entering your information. Look for security signs from Verisign or Cybertrust, so that you know the retailer is not to take your hard earned money.
3. Be careful in regards to the online stores that you consider buying from. If the online store is poorly designed, filled with misspellings, and overall fishy, you should take your money elsewhere. These are signs that something might not be right about this store. It's preferable to be safe than sorry.
4. Always save copies of your orders and receipts from online purchases. Many stores will redirect you to a page after you've submitted a purchase detailing exactly what was bought, customer information, the prices, etc. You should either print a duplicate of this or save a duplicate to your computer in case any issues arise before the end of the return period. Be sure to save any emails concerning your items' status or correspondence with the company regarding your orders, too.
5. When you're shopping online you have to be sure that you know who you're buying from. If you're buying upon 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 to them online.
