My local store was one of the early expanded test sites. I've been using it for awhile now & it's amazing! My local grocery store charges $3.65 for a gallon of milk, whereas Walmart is $1.78. That may not sound like a lot, but I save nearly $200 a year just in milk costs (average 2 gallons a week used in my household). There's no pickup fee (just a $30 minimum) & you're not allowed to tip the workers. AND YOU DON'T HAVE TO GO INSIDE WALMART!
How do they handle item stock? I the home delivery for Meijer and Click List for Kroger but I got tired of having to be by my phone to answer questions "Out of this do you want to substitute the following items?"
Edit: Also I can get milk for $1.29 from Kroger, Meijer or Walmart. Sucker!
