Just been told there is a 'tech' in my area offering gellux tips and polish (assuming gellux polish) for £12! Am I being mad in thinking there is no way she can possibly making anything? I charge £30 for a set of extensions, (don't use gellux though) please tell me I'm not overcharging? After product costs and time not to mention travel I thought it was fair, plus fairly average for my area!
