You have a greatfreegift!  It was a text message which led nowhere and was extremely ANNOYING

I got the free gift from WalMart text too.  I didn't pursue further.  Checked here for others with same experience.  Figured it was a fraud.

I'm trying to figure out how they got my cell number.

Also trying to figure out, what things in common do we all have? I'm a T-Mobile subscriber in the west coast. Have got about 3 texts about this Walmart scheme.
