Want to Buy Bulk roll (100ft) of 35mm rollei retro 400s, rollei infrared, superpan 200 or similar

I need a bulk roll of "retro 400s" or "rollei infrared" or something similar for a project. Any expiration date is fine as long as the film hasn't been stored in Pripyat or someone's backyard in Phoenix. I know that I can buy these new from a variety of retailers but I figured I'd ask here first.
Thanks,
Gram!
