I lose them all the time, but I bought a pack of twelve last year October, and I'm still going strong.
Dunno where the packet is, but there is always a pick nearby should I need one...usually a few on the floor, always one in each guitar case, and others randomly scattered.
I find the best place to look for lost plectrums is in the pockets of trousers or shorts that you werent wearing at the time...thats where mine turn up.
