I got an email a week or so ago saying I won a prize for participating in a survey a while back, and they needed my address to send the check. I was suspicious but I did remember taking the survey, and the company is real. Plus I figured as they already had my name and email if it was a scam it wasn't like they couldn't have easily found my address another way anyway. Anyway a few days passed and I got a new email from the woman saying she needs to fill out a W-9 for any prizes over $400 (I won $550), so I need to fill one out a return it to her, or call her and have her fill it out. This made me nervous as it requires my SSN. So I wanted to know is this legit? Do they really need this form to give me my prize, or is this just an elaborate scam?
