If all these big compenys like manufactures and retailers sold every thing 25% cheeper they would still make millions and millions profit and every thing would be 50% cheeper like apple it cheapest iPhone and most expencef one they both cost about the same to make and they make a profit from the cheapest one so the diffance between the 2 is just profit like i was looking at double plugs a left one was$3 and a right was about $6 so the diffance was profit as they have to cost the same to make
