I had the browser window open from previously checking this deal, and saw it was 8$ last night! Then it went back to 11$ and then dipped to 8$ again briefly. It seems to have stabilized at 11$ and is currently in stock again.
Amazon.com has Fiskars 18" Machete Saw (370500-1001) on sale for $11. Shipping is free w/ Amazon Prime or on $25 or more.
