In July I paid $9.56 for Walmart's Great Value Donut Shop coffee. Less than a month later, it was $15.34. Looks more like 50% or so to me.
I no longer buy Walmart coffee. If I'm going to spend that much on coffee, I'll go with name brand stuff.
I was also drinking the Wal-Mart do it shop coffee but its really not that good. TJ Max sells this K pod coffee called Tall Dark and Handsome for $5.99 for a 12 pod box. Its so incredibly good.
