Sticker Shock

Boy, last time I bought emt tubing, it was like 2 bucks for 3/4 inch. Today at Home Depot, it was 2.97 for 1/2 inch. I really wanted 3/4, but that they didn't even seem to have. The sign said they always had 300 of the 1/2 inch, but there was like 10 pieces there, so I came home empty. 150 miles round trip for nothing.
I will start looking around here. I bet I can scrounge. I know I have 30 or 40 5 foot pieces from some old rabbit cages that I used for legs.
