Has the DVD gone out of print?

I've been looking to order myself a copy of FEMALE TROUBLE on DVD. But on Amazon, it's being sold for $89.99. To even get it used on Amazon is at least $45.00. I've also searched for it on other websites and all of them charge insane prices for it. I've also noticed high prices for POLYESTER as well. Are John Waters DVDs going out of print?so
