Millarkie - Yes, the word From is used quite a bit in marketing of some services. Legally the offer must be valid. Credit card companies often use this method - the APR they advertise is available to SOME PEOPLE, but isn't to all... it is dependent on the circumstances.
The gut reaction is what I wanted... generally speaking, peoples gut reaction is that From £2.50 per hour (per child) is more likely to be better than £10 per hour (per family). Reality however could be that fees work out to the same hourly rate, regardless of the number of children involved.
XcupcakemummyX - Yes, costs for childcare like any other service vary on location, as well as other factors such as the time of day at which it is provided, plus where it is provided. There are other factors as well.
Funnypeculia - Yes, the gut reaction is what I wanted. What I want to try to prove is that the gut reaction when it comes to pricing, can be wrong. But, because initially the human brain usually determines (what factor I don't know, we may get enough answers to start working that out, but I expect it would be 7 out of 10 times) that £2.50 per hour in this case, is the better option, then an advert for a childcare service saying 'From £2.50 per hour (per child)' will get a higher level of enquiries than the same service advertising at £10 per family. Does that make sense?
You may be wondering why I asked for the number of children you had. The reason for asking that, is that I wanted to see if that factor made any difference to the answer. So far, at time of checking, one person has answered B... they have 3 children with one on the way... so with 4 children £2.50 per hour per child, or £10 per hour per family, are the same.
