I am NOT a Walmart shopper. I detest Walmart. They have limited selection, never enough checkout lanes open, crowded aisles...shall I continue? But...they have grocery pickup, and it's genius. I can fill my cart throughout the week as I find out what I need and then schedule my pickup for my commute home. I pull up and the groceries are loaded into my car. DONE. I won't do all of my grocery shopping this way, but it sure is a nice option.
