Looks like a fraud to get you to sign up with something else....Ebay doesn't do that. Whomever is the account holder at Ebay that sent it can have the account suspended for foolishness like that. Sorry, but in 5 years I have never seen any of us able to redirect you in order to claim a gift from an ebay store or to redirect you on winning auction purchase. I would definitely send the link and a copy of the email to Ebay though, if they are allowing it they will email you back and if not they may send you a voucher for use on the site.
