Walgreen's is running various programs with Twitter, including a customer survey about their Balance Rewards program which I filled out yesterday. I then was targeted with the below promoted tweet.
My first reaction to the promoted tweet was echoed by other users: "Walgreen's, are you calling me fat?".
Their tie-in with popular show "The Biggest Loser" has garnered them mainly negative replies by users. I'd say they fell into the trap of trying to leverage another brand's popularity, without considering the pre-existing negative associations with that brand - this has created a juxtaposition between their goal of trying to play in the health and fitness market with the belief many people have that the approach The Biggest Loser takes is "lose weight at all costs".
Key takeaway: chose your brand partnerships wisely.
