With all of Star Trek at $35 a season, we get the rare chance to compare sales. Search for Trek on dvd, then have them rank the sets by popularity. It's a 50% off sale, but it's more like 75% off what Ent and Voy cost at the start of the year. Yesterday, TOS was 1-3, so things can change up pretty quickly. The sale lasts through the end of the month. Last summer, I paid 3x these prices for Enterprise 1-4, but I feel a little better about it after getting Voyager 1-7 at these prices.
