Bought tickets to the Cotton Bowl. 3 hours later my tickets were delivered to my email, I clicked on the link, and realized a code was sent to my email to accept...via SeatGeek - StubHub's competition. I didn't enter the code. Contacted StubHub, re: email's legitimacy, but seems quite odd. The email says "your tickets have been made available on seatgeek". Is this legit and normal for StubHub ticket purchases...redirecting to SeatGeek?
