I just perpetually sign up for blockbuster free trials. I'm on my like 6th free trial in a row. Just slightly change the address and e-mail. 3 my mail with free instore exchange (store is 5 minutes from my house.
Also, the blockbuster kiosk in my publix always has free codes, so I don't really have a need for netflix.
Reminds me, I need to put the cancel in my calendar for next week.
