You can set up a multiple item, fixed price listing on eBay - I've done that where I had purchased a large lot of NOS engine rebuild stuff.
Link to some VW bearings I have:

Similar to your polaroid film, it was mostly NLA stuff that may take a while to sell.
I set up the listing with a fixed price per unit - anytime one (or a few in one transaction) sells, you get an e-mail with the details. Kind of a list it and forget it thing. I think it costs .20/mo for the listing + any final sales values eBay assesses
