This was rather amusing said by the staff of Funimation at Otakon:
QUOTE After bringing out five volumes of Shuffle!, Funimation is now ready to put out the sixth, and final, DVD of the series. While typically, anime series are brought out with collector's boxes coming alongside the first volume, for Shuffle!, the box will actually be packaged together with the last one as an "ender set." A thoroughly unique collectible with that package will be a set of 'God' panties, as worn by Shuffle!'s main character.
