"Last November, Warner Home Video launched their "DVD2BLU" program, allowing consumers to upgrade selected film titles from standard DVD format to high-def Blu-ray Disc, for a smaller-than-retail-price charge of $4.95 per title (plus shipping). Today WHV expanded that program to include TV titles for the first time ever! It costs a bit more for these multi-disc sets, of course, $14.95 to $19.95." Supernatural is included in this.
