Review title: Another Sansone Reissue Product review: Once again Leslie Sansone's fans are being duped into getting a Walk At Home DVD that has been reissued. This is about the 4th time this has happened to me. Check your DVD library and make sure you do not already own this. It was orginally issued back in 2006-2007. The DVD deserves more than two stars but as a long time fan of her exercise program that is all Leslie gets without explaining to her fans that this is a retread.
