I was looking around and found this great sale on Amazon this morning! You can get the
Fiskars 95287097 45mm Rotary Staight Blade 5-Pack for $12.98 with Free Shipping!
I went ahead and bought two for myself. Five blades for $12.98 is a great deal, that is only $2.59 a blade. That should keep me supplied for a while! If you are interested, just click on the link below!
