Quoted from Bud:
How hard would it be for redbox to put up a pop up disclaimer saying all features may not be available on Blu-ray Disc? They have pop up disclaimers for age.
First off, you are right. I wasn't aware that Redbox rentals didn't include the extra features, so thank you for pointing that out.
As for the disclaimer, when they add that it will be on page 42 of their "Terms and Conditions" under an unrelated heading. As I'm sure you're aware, their age pop-up is just a lame legal dodge like the beer sites that make you enter your birth date. I mean, really, if you're under 18 you're too stupid to get past those? That said, the disclaimer SHOULD be somewhere and I didn't find it on the Redbox website.
On Redbox's side, they are targeting a cost-conscious market and are trying to keep their price down. I'm guessing that very few people would select the "includes extra features" disc if it were available as a higher-priced option.
