Agreed, I only bought the $20 Amazon deal at Living Social since it's a guaranteed $10 savings at a company I frequent. Even then, I was hesitant to pull the trigger because I had to go through the registration process and opt-in to spam. While it's not my concern, I don't see how some of these deals by large, nationally recognized companies (ex: Gap, Amazon, B&N) would be sustainable. I'm sure they can charge it to marketing, but they're increasing sales by offering a substantial discount that makes them lose money on short term, small transactions. I assume they hope 1.) new customers are attracted, 2.) customers spend much more than $20, or 3.) customers who don't normally visit are attracted.
