As an avid fan of TV on DVD, I've been consistently surprised over the past few years by how low prices have gotten and how high they can still go. Initially, most TV on DVD was very expensive with one season going for about $75-100 for an hour show (The X-Files, Star Trek shows, the Avengers series). But then prices started going down. You can get the Buffy and Simpsons sets for about $35, for example. However, pricing continues to fluctuate wildly when compared to movie prices. Take these examples: -The first season of Diff'rent Strokes was just announced for $30 (which means you can likely get it around $20 if you look around). Say what you will about the quality of the show, but that's a really good deal for a whole season. -But today I read at DVD File that 7th Heaven's first season will go for $90! Even with careful searching you won't find that for less than $60. I feel sorry for any fans of that show (I'm not one), especially as it goes for a lot more than most of the other family shows out there. So, do you think DVD TV prices will continue to go down or that these fluctuations will continue? And what are some of the best bargains and worst rip-offs out there?
