Back in January 2011, LivingSocial offered a $20 Amazon.com credit voucher for $10. Over 700,000 Amazon.com gift cards were sold in 14 hours. We’re now seeing this same kind of traction with a Starbucks gift card that they put for sale yesterday afternoon. LivingSocial has sold over 700,000 in online gift cards for Starbucks with 11 hours still left on the deal. The deal is set to $5 for a $10 Starbucks credit. I tried to buy it yesterday itself through my mobile device, but it seems like LivingSocial’s servers were slammed. The Starbucks Mobile App sent out a push notification after the deal went live, which explains why the servers went down temporarily.
