I'm not a repurchaser/flipper.
I have three flap-top bins of pedals, tightly packed, and one of the bins has the earliest pedals, etc.
I've taken pedals out of use, tucked them into a bin and forgotten that I had them. And sometime down the road, purchased a new one, same thing. Every few hundred years I'll get a bug to dump all the pedals out of a bin and see what's in there, and rediscover something or find the original of what I've purchased a duplicate. A few of these pedals are now "like, totally, dude, vintage!" and I've had people wink at me and tell me that they understand that I've picked up a new pedal to preserve the vintage version. I only wish I were that smart when just the opposite is true.
