Got a message that says thanks for visiting their website and to call  877- 861-8581 to receive a $100 Walmart gift card.

I received the same text that says thanks for visiting their website and to call  877- 861-8581 to receive a $100 Walmart gift card.

just got this message also..I don't give out my cell phone number.

I also received this message, "Thanks 4 visiting Our Website Please call 877-861-8581 to Claim Your $100 Walmart Gift Card Voucher! Reply STOP 2 Unsub"   I do not think I gave my cell phone number to any website.

They are probably using a robo-dialer that calls every number.  

The gift card is a scam.  They'll find some way to make you pay taxes or shipping or something by credit card.  Then they'll use your card number to spend your money.
