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 purchase from people that have positive feedback. On other sites look to see should they be a reputable company by searching for reviews on them online.
3. 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 everything that was bought, customer information, the prices, etc. You should either print a copy of this or save a copy to your computer in case any issues arise before the end of the return period. Make sure to save any emails concerning your items' status or correspondence with the company regarding your orders, too.
5. A good online shopping tip to remember is always to leave feedback after buying from a source you've never bought from before. This will help the two of you because you'll remember if you've enjoyed a good experience from them, and they will also acquire a reputation as a seller.
