Minor nit-pick. Groupon doesn't make money on the float. They give the money to the retailer pretty quick. My understanding is the the retailer gets paid even when the groupon isn't redeemed. One would think the retailer would make up some money on the non-redeemed groupons, but groupon claims a higher than 90% redemption rate. Other than that I completely agree about service businesses. I saw a local bike shop sell over 1000 tuneups for $7 each. Meaning the bike shop received $3.50 for a tuneup, and their techs would be booked solid for a long time preventing them from being able to perform as many higher profit services.
