On August 10th of 2012, along with the MMPR complete series set/seasons 4-7 bundle, Time-Life offered a 6-disc set for the complete first season. Last week on March 10th though, along with releasing the complete PRLG season, Shout! Factory put out a version of the complete season 1 set as a Wal-Mart exclusive. It has an MSRP of $14.99, and the cover art looks different. It uses the image of the MMPR season 1-volume 1 set, has a blue background, and has a peel-back graphic on the upper right-hand corner of the front cover stating that it has six discs. Wal-Mart currently doesn't have a listing for it on their site, but some other site shows the front cover.

Amazon's Canadian site also has a listing for MMPR season 2, which they also made available last week on March 10th.

Shout! Factory seems to also have plans to release that as a Wal-Mart exclusive, but they don't have a set date for it yet.

On the legacy set front, it started off at $650, then went down to $500, and then $400. When it was at $400, there would be the occasional sale that would knock the price down to $320. Now that seems to be the new standard price.
