That's an interesting question.............the one about lower priced service having more loyal customers !
I've always been lower to middle pricewise and in spite of NOT ADVERTISING for at least 12 years I still get regular customers using me and ,,,,,,,,,,,,If I left cards or leaflets would probably have at least double maybe treble the number of repeats.
I'm hard to find but still get people taking a lot of effort to get in touch. I don't believe it's all about cost - everyone knows I increase prices slightly each year - but I DO STRIKE A STRONG RAPPORT with most of my customers and this has given me loads of referrals to relatives, neighbours, work colleagues.
