I don't know what the ChemDry franchises do on pricing but their managed network (Homeserve ChemDry untill they change the name) have run these offeres for ages but the core prices are very high. On the "get your suite cleaned and we will clean your lounge carpet for free", the per seat price is £40 with protection extra. Most of their offers follow this principle.
Well i have to say, i was wondering. Its like that company who claim to give you the windows for the back of the house 'free' when you get the front done.
The tragedy is that many people do truely think they are getting something for nowt 
You've got to hand it to them really, but big players in ours (ChemDry, Servicemaster, Ovenu) and a host of other industries (Everest, Moben etc) will always have a following and seem to be trusted. When we wanted a new bathroom fitted, the first people we went to was "Dolphin" £13k for them to fit a bath, sink and kahzee, no tiling included cos they said they didn't do it... Did we pay? Did we hell, but I reckon if we had more money than sense, we would have.... :

Let 'em have it I say, there's enough work out there for every one of us and maybe we should concentrate on how we're doing instead of worrying about other C/C's, independant or otherwise!
