Always bear in mind that it is not the investment you make that can jeopardise your finances, but the fact that the investment does not bring you the results you had in mind. People buy services or products because they think that the sales person understands their wishes and not because a sales professional insists until they understand the application of the product. Sales processes are often tedious, especially when what is bought is not immediately enjoyed.
Leave aside logical concerns such as, will everything be explained to me in a way that I understand and have no doubts? Am I buying the best product at the best price? Will the product meet my expectations? Will the company
deliver everything the salesperson has promised? Will the service match the quality of the product? Will I be attended to when I have a problem?
