I read this and I guess you have to walk in to Verizon to confirm this:
"Update: We just confirmed through a second store connection. They also pointed out that if any of you purchased a Galaxy Tab within the last 14 days for $599, you should head back into the store and get a refund of $100. Sweet deal."
