The $500 fee for the Basic Acoustical Package can be used as a credit toward the purchase of treatments specified by our designers. This offer is limited to the quote that was specified and is only available for 6 months after the quote date. The fee will be listed as a credit on the quote but does not exist as a standing credit on your account; this fee is not refundable otherwise.  This offer is not included with any of the other design packages.  Only with the Basic Acoustic Package... sorry.
