Hi,

A part of my current job role is to order lunch for the training classes we provide. I was hoping to get some affordable catering recommendations. I usually just rotate the same three lunch options (sandwiches/pizza/ Chinese platters) .

I rarely go to Walmart but I stopped by a few days ago. I did not enter my phone number but I still received an email about my visit. How does Walmart know I was there?
