I find in past years it usually starts to slow down for us around the end of this week. 

I have more products than what i have to offer now then say last christmas too, so its hard to really know because my listings have almost doubled. I know i have had a better christmas this year than last, i think people are leaving their christmas shopping till later plus the ebay fiddling, the rush started later than usual, i cant believe not so long ago i was complaining how dead it was and then all of a sudden wham it was going crazy.
