There comes a time when enough is enough. Just how many flat blade screw drivers do you need to have, two: a right hand one and a left hand one 🙂 I have about 20 of them! I've been cleaning out stuff I will never use or need. Original AC Delco Spark Plugs for my 81 Vette , trash. Original AC System and fan/shroud for the SS with brackets, bolts and lines: gone for parts credit to a G Body parts store. So now that my Little Garage Attic is clean of old parts, I will not save any more. As far as material cost, where did you hear prices will come down? So will the .35 cent gal of gas! IF you got to build it to make more room you are ;looking at the the wrong way. Get rid of stuff. My next task is the boxes of Christmas lights that have not been strung about for over 7yrs! Getting too old to climb ladders.
