I'll be in NYC next saturday, and I need to buy some 35 mm films (in
particular, slide : Kodak E100VS and film : Ilford HP5 or Kodak Tri-X).

B&H (www.bhphotovideo.com),

I'm pretty sure B&H is closed on Saturdays. But I would think
you could pretty much walk into any camera shop in NYC and get
E100 or HP5+ or Tri-X. It's that way in Bawlmer...
