1. Be careful when it comes to the online stores that you consider buying from. If the web 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.
2. Always save copies of your orders and receipts from online purchases. Many stores will redirect one to a page after you've submitted a purchase detailing exactly what was bought, customer information, the prices, etc. You should either print a copy 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.
3. 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 buy from people that have positive feedback. On other sites look to see should they be a reputable company by searching for reviews upon them online.
4. Whenever you enjoy the comfort of frequent online shopping, it's essential to keep changing the passwords you use for each and every account. Every few weeks or so, make up a whole new password for the bank and the shopping sites directly. Use abstract words, combined with numbers and other odd characters for that strongest passwords.
5. Sign up for your chosen online stores' newsletters. Often times online stores will send out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to spend less, you might be able to score some terrific deals on items you were going to purchase anyway.
