So basically, that copy of Blade Runner you bought 3 years ago? The Director's cut plus? Well, that was then, now we have a completely new product, Director's cut plus enhanced, with a never before seen napkin drawing of Roy Batty's potential haircuts that never made it into the movie. So yeah, we don't carry the old one any more, but if you want the plus enhanced, that'll be another $19.99 please.
Don't for a second think these a-holes are doing anything for YOU, the consumer. Just like the insurance industry doesn't give a shit about giving you actual medical care, these people don't care about giving you anything - it's all about their profits... perpetual and guaranteed.
