I really liked the war eagle finesse spinnerbait this year and found that I could get the wide willow leaf blades I wanted in the smaller sizes at Jann’s Netcraft. The bummer is that it’s 12.12 for the blades and 9.15 for shipping. Don’t hit free shipping till 150.

Does anyone know of a source for these blades that has a lower bar for free shipping? Worst case I just do it and mentally block out the shipping charges. 

Magnum willow blades also called Oklahoma, wide willow, and other names. are the preferred blades for salmon fishing in the northwest, and Alaska.  There are many mail order shops in the Northwest that sell any size and color you could possibly want.  Two I like are Fisherman's Shack Don is the owner and will be the one who answers the phone. He will give you a deal on shipping and almost always throws something new in for free.  He has way more inventory than his web site shows.  It is best to call him and tell him what you want.  Spinner Dave's has a more modern web site and catalogue.  Google Salmon spinners and parts and you will find many more.  Barlow's, Jann's Net craft and Lure parts online, are more well known national mail order stores that carry Mag Willow blades.
