Just wanted to let everybody know that I was at Costco today an it seems that they are running a promo where if you but "The Twilight Zone" season 4 with any of the other previous seasons, you will get a $25 discount off the purchase. I'm not entirely sure if it is at the register or if it is mail in thing though. Obviously, the two sets must be purchased on the same receipt. Costco is selling the sets for around $55. So already it is pretty much the best price you can get these sets for anywhere that I have seen. I still have my Costco purchased season 3 set unopened and still in the long box. I am going to try to return it and then just re-buy it with season 4 and get the discount.
