There is a new Redbox code for a free game rental through 10/28 only. It’s advertised on their Instagram page so it should work for everyone.
I tested it online and it worked perfectly for me.
Just use code: TRYB4UBUY.
On occasion these codes don’t work when you just drive directly to Redbox so please take that into consideration. I recommend going online first and reserving your game at the location of your choice. You can confirm the code works and pick up the game at your convenience.
Please note you will need to return the game on time or they will charge you a second night rental.
