My wash I just opened is 1.50/4min and vacs are $1/4min. The other one is priced low at $1.25 for 4:40 and vacs are $1/4min just raised from .75 last year. I want to raise prices but it does really well now so I don't want to mess around too much. I once had an accountant tell me though, about a different business entirely that I was lamenting about high volume and trouble finding enough qualified help, that maybe I should charge twice as much. I said "but then I will lose business". He said "exactly, but most likely not half" I still think it is a sound principle. Probably run off some of the less desirable customers too.
