Be on the lookout for fake gas gift cards. Better Business Bureau (BBB) Scam Tracker reports that scammers are tempting drivers with phony gas station gift cards to steal credit card details and other personal information. You see a post on social media, get an email, or take a survey that says you won a $500 gas station gift card. The scam claims to be from Shell, but watch out for scammers using different gas station brands too.
