I needed an extra binder once (some Harris WW album, can't remember which one, now) and looked and looked at all the stores, websites, etc for a new one. No dice. I also went to
eBay. I finally found a collection in one of the albums and the binder looked pretty good. It was a cruddy collection and the album went for a song. When I got it, I pretty much chucked the pages and the stamps.
