Can i still get polaroid SX-70 film any where even though it's discontinued?

I just got an old polaroid “pronto” SE camera from the mid 80’s. Originally it was made to be used with SX-70 film but will take 600. I’m curious to see what the product will look like with the old film though so i’d like to get my hands on some. Moreover, since the film was discontinued in 2005 do you think any stock of it I get will still have the same potency?
