There were a number of smaller rental shops in the Chicago area that carried them. Family Video comes to mind. I don't believe the Blockbusters by us ever had them.
I still have my laserdisc player, they are becoming a harder to find item for reasonable prices for sure.
I started collecting Laserdiscs a few years ago after having grown up with them as a kid in the 90s (we only rented them, because new laserdiscs were expensive!) - With the inflated cost of used Vinyl these days, it's been fun collecting Laserdiscs of my favorite movies for their artwork and form factor to display alongside my record collection at a fraction of the cost of Vinyl. Also it's a weird hobby that I find hilarious to tell people and see their reaction. Most people don't even know or remember what a laserdisc is/was. Anyone else love Seinfeld's Laserdisc joke on the last episode of Curb? Who says Laserdiscs aren't cool?
