Between now and the end of November, anyone who checks in at one of 20 Duane Reade locations in NYC and mentions @EBOOST will win a special edition Amar'e Stoudemire t-shirt. EBOOST Healthy Energy Drink As if that weren't enough, one lucky Foursquarer will be randomly selected to win $150 worth of EBOOST and a pair of Knicks tickets! Who says nothing in life is free?
