HITS estimates: Kelly 33.8k, Cook 26k

Three Idol alums saw their albums appear on HITS Daily Double's Top 50 building album sales chart this week, led once again by Kelly Clarkson.

Kelly's All I Ever Wanted fell seven spots to #14 with 33.8k copies, marking a 33% dip in sales. That was six spots ahead of David Cook's self-titled album, which re-entered the Top 50 portion of the chart this week at #20 with 26k copies.

The only other Idol alum and coincidentally the third winner represented on the chart was Carrie Underwood, whose Carnival Ride stayed virtually unfazed at #32 with 16.4k copies, holding level sales-wise.

Final numbers courtesy of Billboard should be out by the end of the week.
