Hi,
I'm not sure that dvd rental or purchase places are a thing anymore but yes dvd's are still a thing even though most laptops now don't even have the space to insert a disc. I guess go on your local buy/sell/swap page, borrow movies from family/friends and maybe visit your local library and they may have some other than that, buying a dvd in a store i.e. target, wal-mart, kmart etc (depending on were in the world you live).
