The only freebies that I routinely get through company newsletters are these free Blockbuster Express Rental Codes. A code of GA13B1 was sent out today and it expires on 3/24. If you rent movies from these kiosks frequently, you might want to consider signing up for the newsletter.
Actually, wait, don't do that. Why am I helping make my job obsolete? Ignore my previous advice and, uh, instead get rid of your computer! There, now you can't sign up for that newsletter.
Wait a minute, then you can't read HIF. Ugh, I honestly never got the hang of this self-promotion business.
EDIT: There's also a code of G213A1, but that is good for today only (Wednesday, March 10).
