I received an e-mail with a free Blockbuster Express Rental Code of GOLIVE, which expires on March 3. The e-mail was about how BE now lets you reserve movies on-line and pick them up at the kiosk, so I'm not sure if that's what you'll have to do in order to use the code, but better safe than sorry.
There's also code BBXCES, which expires Feb. 28. I gotta say, these codes are putting Redbox to shame. It's like there's a new Cold Freebie War brewing between the two companies. I've got my money on Blockbuster, but then again I'll probably switch sides as soon as Redbox releases their next code. What can I say, I'm fickle. I'd make for a horrible soldier, and that's without taking my fears of guns, dirt, or loud noises into effect.
