Duane Reade tests weather-based mobile promotion

Duane Reade is testing a new mobile app that will alert customers about impending weather and send them offers based on the forecast. 

Duane Reade has teamed up with Poncho, a personalized weather-forecasting service that sends users relevant weather updates via text or email, to offer the service. Users will receive weather alerts that include messages for sufferers of seasonal allergies with special notifications on days when the pollen count is particularly high. On these days, Duane Reade will send discount offers that can be used for specified allergy-relief products available in Duane Reade stores. Story
