yup. since the 70's but they were in arcades and atari (settop pong even before that) but you could get them as low as 19 cent loss leaders into the 80's. It was not the normal price but if you watched the ads you could pick them up often enough. Also almost no one made minimum wage. If it was your very first job and you were a kid you did for a time but if you showed up on time and sober consistently you would get at least a nickle in 6 months and thats a minimum. so it was not hard to be making four bucks and hour which sounds low but with the price of things it was pretty decent and this was pay levels that no adult was living off of. It was pretty much exclusively kids and college students working part time. Full time positions paid significantly more.
