Need COPPER Pipe, Scraps, Cutoffs , etc for a project


I am trying to complete a project and need some COPPER PIPE is small lengths.
1", 2", 3", 4" diameter pipe in any schedule (K,L,M)

Any plumbers have left-overs I can buy cheap?

Anyone know of a SCRAP yard that might sell copper pipe retail? Most seem to have stopped recently.

Even pipe with ends or elbows soldered in can work for me. THANKS!!
