Warner Home Video has announced that their DVD2BLU trade-in program (whereby you can upgrade DVDs to Blu-ray versions for a small fee) now includes TV show sets.
Their list includes several of my favorites, the first two seasons of Chuck and both Pushing Daisies seasons. Also of geek interest are Fringe (first season), Terminator: The Sarah Connor Chronicles, Smallville seasons 6-8, and Supernatural (except for the second season, for some reason).
It’s $14.95 or $19.95 a set — newer ones cost more — or about a $10-15 savings off of what Amazon lists them for. Don’t forget to figure in shipping, which is $4.95 an item or free with $35 or more purchase. The way the process works, you fill out your shopping cart, send in your existing DVDs, and wait a month to get the Blu-rays in the mail.
