> groupon users only ever get the cheapest bottle, if any. Yeah, because absolutes like this help. Groupon customers can be just like any other customer out there. Some "regular" customers will get cheap wine, some will get an expensive bottle. Similarly, some Groupon customers will get the cheapest wine, others will take the money they saved by getting a Groupon and get the expensive wine. Being a "Groupon customer" might move the needle towards one direction but it's far from absolute the way you're making it out to be.
