Warning
I received a call from 770-799-6261, they hung up before I answered. I called back and the rep stated they were giving away $100 gift cards but they required a $3.99 processing fee. They wanted a credit or debit card #, along with name and address. I hung up without giving them any info. They said the gift card was good at Walmart and other stores and that this was another way that Walmart advertised. I asked how they got my name and number and they said it was from my shopping at Walmart but Walmart doesn't have my personal info.
