"Hoarding" or buying in bulk? Well...when the discontinuation of E100G and E100VS was announced, I picked up about 700 rolls in 35mm and 120 format ("securing supplies," if you will, for a two year-plus project). Generally, though, in order to "write down" the cost per roll, I generally buy my Pan F+, FP4+, HP5+, and Tri-X in 100 roll lots (and will probably do the same in the future with Velvia and Provia). Hoarding? No...not really... lol
