Groupon is a bust, unless you're doing 1 room for $69. What we have to realize is the % of people that actually care about the quality of the job you're doing is probably < 1%. The rest are just calling you because of the deal they are getting. They don't care if you're doing a 12 step process or a 2 step process, they just want what the groupon gives them. Also, no matter how affluent they claim their client base is, it's clients who let their carpets go years w/o cleaning and now expect the most pristine cleaning for whatever the groupon is.
I'm glad I did it, I was able to experience a lot of situations and try different chemicals, however, I would never, ever, do it again.
