Research companies you deal with
When you’re online, a little research can save you a lot of money. If you see an ad or an offer that looks good to you, take a moment to check out the company behind it. Type the company or product name into your favorite search engine with terms like “review,” “complaint,” or “scam.” If you find bad reviews, you’ll have to decide if the offer is worth the risk. If you can’t find contact information for the company, take your business elsewhere.
Don’t assume that an ad you see on a reputable site is trustworthy. The fact that a site features an ad for another site doesn’t mean that it endorses the advertised site, or is even familiar with it.
