i would say check ebay i use no name blades from where ever is cheapest i buy blades for myself plus blades for a group house we quilt at and we go thru alot of blades i try to stay with the titainium blades as they seem to last longer from experience. but you can get named brand blades much cheaper there too. i usually order my blades in a qty of 10-20 at a time and from a bad experience with the post office once i never wait til the last minuate i did that once and it took 3 mo to get them the seller had already sent a replacement. i must admit i havent tried the new endurance blades from olfa yet ive been watching for them to go on sale and just havent gotten around to it yet. i tried the harbor freight blades and wasnt impressed either. im not patient enough to do the sharpening thing.
buts thats my take on blades lol.
