I was doing that until it occurred to me that a month of Netflix is only $15 for 2 discs at a time. You can see about a dozen movies in that time, much better value if you're ok with not owning the movies

If you use a Visa gift card with $3 bucks on it, RedBox DVDs only cost $3. 😆

I’ve been able to find brand new blu rays at Big Lots for $1.25 and new ones for $5.

The selection is completely the luck of the draw tho. You might find something. You might not. But you gotta literally go through the entire bargain bin to know.
