HITS estimates: Kelly 11.6k, Carrie 10.8k

There were slips and slides to be had all around by Idol alums HITS Daily Double's Top 50 building album sales chart.

Kelly Clarkson kicked things off for HDD with her latest album All I Ever Wanted, which sold another 11.6k copies, down 9%, and fell two spots on the chart to #42.

Next up was Carrie Underwood, whose Carnival Ride dipped 12% in sales to 10.8k and was only down one spot to #44. And David Cook's self-titled post-Idol album took a sizable hit to #44, down from #26 the previous week, which was a 44% sales dip.

Exact figures will be available as soon as the Billboard 200 chart is made public, which should be later this week.
