I was rather amazed that the goods I ordered arrived in less the twenty four hours after I ordered them. Well done for that. Since I have not bought spark plugs for a few years to change them my self I was quite confused that the price of them before the discount was applied, that I mistook that the price was for only one not for four which is what I needed. I think this should be made clear that one is for one spark plug not one for a set of four spark plugs. I did get it solved by buying three more from one of their outlets in the town where I live, the next day, So all is well that ends well.
