And know what you’re getting into. There are dishonest people in the bricks and mortar world and on the Internet. But online, you can’t judge an operator’s trustworthiness with a gut-affirming look in the eye. It’s remarkably simple for online scammers to impersonate a legitimate business, so you need to know whom you’re dealing with. If you’re shopping online, check out the seller before you buy. A legitimate business or individual seller should give you a physical address and a working telephone number at which they can be contacted in case you have problems.
