WCA (Worldwide Commerce Associates, LLC) operates the Special Offer Service, a unique subscription-based program that rewards consumers for consenting to receive recorded messages that include special product offers and purchase incentives.  
The SOS program was created in order to comply with state and federal regulations that govern the transmission of automated voice messages, and WCA is committed to making it a positive experience for all subscribers. (yeah right! Unsolicited is not a positive experience for me).
