I don't think it's as important as you may think it is. I prefer five day auctions so I don't need to wait as long. However, I try not to end on friday and saturday nights.
I agree with this... I for one spend Sunday night with my family and perusing ebay is the last thing on my mind. Unfortunately I have missed many an auction because I spend my weekends doing fun stuff. But it is sooooo worth it!
On the other hand, sometimes people like to bid at the latest possible point in time. So if a guy is going out on Friday night, he will place his bid before he leaves even though it's a couple hours earlier than he would have like to bid. Then another guy does the same thing, and your item is way up there. Now you just hope that there is a third guy sitting there waiting to bid! Ebay is such a strange creature, sometimes items that end at 4 am sell for less than normal, but sometimes the opposite is true and it sells for more than ever. There is sort of an element of luck involved when selling on ebay.
Besides, these days with snipers all of these points are practically moot. You just have to hope the right people see your auction, and if they have 7 days to see it, well, that's 2 extra days for them to catch your auction.
What I despise is 1 day auctions. Who knows how many items zipped past me like that. Probably the #1 cards on my wantlist, but I don't like to think about it.
