Good people at #animedvd passed a tip that Bandai "solicited" Rocket Girls: Complete Collection to be sold for $49.98, with the street date of 2008/10/7.
The anonymous benefactor bayoab also reminds that the price is ususally quite a bit less than the MSRP. I'm so in.
UPDATE 2008/08/20: Robert added a section. The price is $36.98.
