Home Depot: Diablo Steel Demon 9-inch 8 TPI Carbide Reciprocating Saw Blades, 2-pack, 9.21 liquidation YMMV

For cutting thick metal, cast iron, etc. I need this as I'm cutting 4" cast iron drain pipe and my Dewalt bimetal blades are barely making a scratch. Regular price for these Diablo blades is about $20 each, so already this 2 for 1 pack for $19.98 seems decent.

But in-store (L'Acadie store #7146) it was on a liquidation rack, around the corner from the regular shelf with the other blades, and marked down to $9.21! So of course I got 2 packs. There were 3 packs remaining when I left. YMMV.
