Hmm, possibly. These deal sites (Groupon especially) have always been pitched to me as a way to find out about deals at places you don't go often. For me, I know all of the small shops (that's all our town really has, our ban on drive-thrus really stops the chains from coming in) and I know which ones I like. I visit often enough, so when they are having sales or events, I know they are going down because the cashier told me last week, or I saw it on a sign as I biked to work. Do you have any links explaining the "group buying" in china you are talking about?
