Not in Flushing but in Queens, Pacific Supermarket at Broadway and 75th St in Jackson Heights had them a couple of weeks ago. (After looking at the other thread, I'll note that these are the inexpensive bagged sort, nothing special.)
I saw these in the large chinese market on 8th Ave and 63rd St in Brooklyn. Sorry, not Flushing. They were in the dry foods isle. Just labeled chile, but they were the facing heaven kind.
