Walmart is the well known name and brand they are using. The text is not associated with Walmart. Its a trap and resembles a ponzie sceme. I did not look deep enough to find the actual groups using this solicitation device and means. However, its clear that you'll go far into a rabbit hole and get trapped, wish you never started and still in all likelyhood not recieve the reward you jumped all the flamming hoops for. They use words like "Offers might require you to *****Open a Credit Card and Transfer Balance******* Major tip off there.
The Scam is similar to a ponzie sceme and has traces of much worse. They ask for email, but using the full text web address will most likely link your phone as responding. Its not asociated with Walmart, Verizon, Best Buy, or any of those well known highly profited companies. They use those companies to lure you in. I often elude to a rabbit hole in my posts. This is one of those rabbit holes.
They will require that you complete 6 offers of questionable content, reliablity, security and have language that really sets my hairs on end. "Offers might [my thoughts: might = will require] require ****Opening Credit Card and Transfering Balances*****) You have just invited someone to steal your information, drain your banking account and ruin your credit score.
Note: Its a sceme, Website is a trap: you will not experience errors or unwanted messages until you try to leave.
