1. Sign up for the website's newsletter if they have one. Many times stores will give you a reduction or some form of deal when you sign up for their newsletter. Determine if there is a deal associated with registering for the newsletter at any store you need to shop at.
2. Make sure that you're entering your payment details on a secure site. Try to find "https://" inside the URL from the site that you're attempting to buy something from. If you don't see that or no sign of any website security, then it's probably a good idea not to trust those people along with your account information.
3. Pay close attention for potential sales online starting as soon as Wednesday. Many brick and mortar stores do sales on the weekends, and to compete, many internet retailers have moved their sales days up by several days. You can often find exceptional mid-week bargains with just a little online research.
4. A great way to stay safe when shopping online is to avoid clicking any web addresses that are sent into your email. If you are expecting an email from a company, proceed to the actual website and do not click any links. Legitimate businesses do not send emails asking for personal information or account information.
5. Be careful in regards to the online stores that you consider buying from. If the online store is poorly designed, packed 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.
