Problem with KMC outer sleeves

So I love KMC sleeves. The feel is great, the size is perfect, and the protection is great. Only problem, and those of you with KMC sleeves know this already: the outer sleeves only come in packs of 80. So I have to buy 80 more outer sleeves for 20 more cards. Good business strat, not so great for the consumer. So what do I do with the other 60 sleeves? I've mostly been using them for draft sleeves, but I don't draft that often outside prerelease. Is there something I can do with then besides keeping them in my drawer, or should I just suck it up and use the same color for more than one deck?
