- Wal-Mart is $3.18/gallon
- The Pig is at least $3.30
- Kwik Trip is $2.60 - (I found this to be $2.36 lately, and you have to take into consideration that you get $1 off every 10 gallons. They also put out Internet coupons once a month on their email list for $1 off)
- Sam's Club is $2.55.
Thanks for your research Sara! I added my comment about Kwik Trip - the bag milk is the preference for me there, unless it goes on sale somewhere else.
