I used credit my credit lines and bought from Adorama, Samy's and B&H:

35mm Fuji Provia 100F
35mm Kodak E100G
120 Fuji Reala 100 (you see my stash here)
120 Kodak Portra 160 (almost as big as Reala stash)
120 Fuji Provia 100F
120 Fuji Velvia
120 Kodak E100G
120 Kodak E100VS
4x5 Kodak Portra 160
4x5 Kodak E100G
4x5 Kodak Tri-X 320 TXP
4x5 Fuji Astia (last box Samy's)

Aside from the TXP 320 these are all slower emulsions by design. I further determined what to stockpile based on looking at my old stuff and also considering what is likely to be scarce in not too distant future. Most crucial for me was scoring some medium format Reala and Portra 160.

Total dent in the financials is about 5K. I am not married and don't own a car - which explains it.

I sincerely hope that the Lord (or Santa) blesses all of you with the funds (or credit) at the right time to stockpile your favorite films as well.
