Long wait, hmm? Maybe you're quota'd or something. I switched it to top of queue, it's mailing today.
Anyway, as for finding it in Redbox.. yeah, the downside to kiosks is that there is always going to be a limitation. Blockbuster will suffer the same limitations when its kiosks are more prevalent.
The future, folks, is digital streaming. We're getting higher and higher bandwidth, and the studios are going to eat up the ability to "control" who gets what , when, and how. They're going to love being able to send you a bill every time you watch a movie, and you're going to love the extra library.
