I also have received several identical postcards saying they've been going crazy trying to contact me and that I need to contact them to receive my two complimentary roundtrip airline tickets to anywhere in the continental US.

Rec card with the same general info, but for me to call that number and get two free round trip tickets for anywhere in the continental US "In celebration of our (their) anniversary". Decited not to proceed with the "invitation".

Offered 2 Southwest plane tickets on a post card.
scam.

Received a post card with this number. The card invited to visit a presentation. After doing some research I found that this is a scam that has been around for a few years. The scam is in the free gifts. They are not free at all. The presentation is for a buying club that cost $3000.00 to join. This company is also known as GSN Global Savings Network, and is based in Dayton Ohio and also Houston TX. STAY AWAY!
