Okay, so I bought TOS last summer. Now I am in the Process of buying TNG since the price has dipped. I have Seasons 1 and 2 and seassons 3-5 on the way. But why are Seasons 6 and 7 still at such high prices?? And I have noticed that with Voyager and DS 9 as well and Enterprise is still too expensive for me Any idea when the MSRP will dip on this?
