Signature series open box deals at Slickdeals -Adorama

Options
This may be a few days old already but I noticed Slickdeals is showing several different packages for open box Signature series speakers - with a HTS sub. For example, one deal was a pair of S55, a S35 center and a pair of S20 with a HTS 12" sub reduced from $1710 to $899 with free shipping. Other packages seem to be available from Adorama. Slickdeals site has details.
