- RPRealEYEz Awakened PerspectiveApr 27, 20265.0Clean store and Restrooms. Friendly staff nice vibe, at the Walmart close by!
- KIKeegan IkeApr 25, 20262.0Just found out about the new penny rounding they do for cash transactions here. They don’t round to benefit the customer, the round to benefit themselves. I saw no signage about the rounding of change for cash transactions. Either change your prices to end in nickel intervals to give a true price, or give me correct change.
