I've bought three 100-packs of blades and tried about five of each, leaving me with an incomplete pack of a bunch of blades. I'd like to sell them (at cost even), but I don't want to go to the hassle of selling them piece by piece in terms of the individual 5/10 packs. I don't really want to exchange them, because I found the blades I need and am set for blades for a long time. Does anyone have suggestions what I can do to try to recoup some of the cost of buying these packs?
