I studied by working in corporate america for about 7 years before launching own company . Take an entrepreneurship classes or marketing . Business Admin doesn ' t really prepare you you can eventually hire someone to manage your books . Most importantly , study successful people . They aren ' t successful by accident . Most will preach work work work work . you don ' t want to follow those people , they aren ' t us you ' ll burn out . Just be interested passionate about whatever your doingselling . Be interested in other things too . <| sep |> I believe not lawyer etc etc the rule or guidance for this sort of thing is that the original or reference price for an item should have been charged for at least as long as the sale is running . I think it ' s also possible that in the case of a chain store they only have to have charged that amount in some stores or a certain % of stores . I don ' t have anything to back this up so take it with a grain of salt , this is just what I ' ve heard in the past .
