As today is the official release day, I've been tracking the rankings on Amazon (as I always do) throughout the day since midnight. As of 9:00 PM, Here's Lucy Season 5 was ranked #554 among all Movies & TV releases, and #46 in the Comedy DVD category. Among all formats (including Blu-ray and VHS), it is #258.

Note that Season 4 reached #164 in the Movies & TV category, compared to the current 554th place for this set, which is the highest I've seen it. That's too bad because S5 is somewhat better than S4, in my opinion. But The Lucy Show Season 5 only reached 1,366th, from what I saw. So this is doing much better. However, TLS S5 was hindered by the fact most of those episodes were already available in cheap public domain releases, whereas these are not.
