I agree, MB -- $45 is reasonable for these boxed sets of TV series. It's just that it adds up to a lot to get the entire series, but it gives one something to work towards. A sort of life goal. (And then, you can't take it with you ...)
Most of the DS DVD sets at amazon are priced $53.98, which seems odd since at least two people in an earlier thread, "Dark Shadows on DVD", talked about amazon charging about $44. Have they raised the price? They had a couple sets for less, but most of them are listed at $53.98.
I know there are other discount places, but I just know that amazon is very reputable and I'm surprised they charge that much. I also checked with my local Borders store, and they are charging $59, same as MPI! I have a 25 percent off coupon good at Borders through tomorrow so I may have to shovel out my car and race over there to buy one set (and then cut up some of my credit cards!).
