Found one place online called Frawleys Saw Shop, they sell Oregon loops and 100 ft. rolls, I did the math on the rolls and it figures to about $5.00 savings for me, on the .058ga., .375p, 72dl, and that loop here cost $18.00. Also 72dl is just under 4ft. of saw chain for one loop, I use 2-3 loops/year, that will take me a while to go through that, a grand savings $125.00 in ten years or so, WOW! Then if I figure in climate change, global warming, end of the world in ten years, and bigfoot still on the loose, I'll stay with buying loops, 2-5 at a time.
But if I buy 100' of Forester brand saw chain that everyone says is junk, my savings would triple, then again if I have to file on every tank full of gas, I'd waste more time and have to buy more files, this Oregon chain I'm using now, after 4 tanks of gas, I still haven't filed it yet, and I've cut through some muddy branches, still cuts fast.
