I agree with Klassy Klaws, getting the exta money out of people is a hard task, ezpecially these days.
I've tried puting a charge of £15 for the minx( on top of what ever nail service they've had) and nobody seems to be interested.There was a slight beter response at £10.
Minx are not cheep to buy but you have to make a profit and justify your time.
I've tried all the sales talk about how they last, and how good the designs are but the the answer i get generally get is 'well i get that length of time out of the nail varnish anyway so why pay more and if I want something added I can have nail art'
I might have to have a think about my price list/menu in general to make the minx more appealing.
Mayby I will get more luck with summer coming because a few have said they would be more interested in the minx on toes.
