Well we can go in and buy stuff from the scrap yard too.... Bought a complete go kart that someone backed over in their car. Broke off the right rear axle and wheel, slight bend in the nerf bar.... NO big deal.... I got it at the price of scrap weight.... It was like $15..... (pennies per pound)
I drive up to the scales to get empty weight. Then I go "shopping" for anything of use or value,for my numerous projects and hobbies. People scrap good stuff. There is NO denying it. I'm one of the people who take advantage of that.
Case in point... The day I got the go kart, I also scored an edger that ONLY needed the carb cleaned and blade sharpened. I got 1 fairly new Olympic weight bar. A 15 gallon gas refuel station,with a slightly dented top. They retail for $120, and this one was not even a year old..... Via D-O-M stamp.... I also a bunch of sheet aluminum .120" thick.
I paid less than $35 for the "steel scrap" and $45 for the sheets of aluminum..... That was one HELLUVA score. I still have/use the fuel station. The edger I sold the engine off of for $40. The kart, I fixed and sold for $200. The weight bar, I donated to my fire department. And I'm still using the Aluminum..... You will see some louvered aluminum panels in my build off kart.....
