Tom Thumb was always somewhere I shopped for Milk. It was close, didn't buy much else there, not much difference between Kroger's or Albertsons, it was just closer...
Then along came Aldi's...In the beginning their Whole Milk was almost a buck, I loved the taste and it is even closer than price-gouging Tom Thumb. Sure, Aldi's Whole Milk isn't as inexpensive as it used to be but it actually tastes better and saves me time and money and is less expensive than the competition.
Why should I buy my Milk from Tom Thumb if it has no upside or benefit for me?
