Walmart shopper found $3 shoes, then paid 6 times the price at checkout(nypost.com)

  When she scanned with her app in front of the manager, a whole new set of prices came up. “Where are these prices coming from? So now I’ve got new prices. Different price in the back, different price at the register, brand new prices at customer service.”

  After an hour of dealing with just the shoes, the manager tells her that the shoes simply won’t ring up for $3 — but Kat wouldn’t back down.

  “We’re not doing that again just because you’ve now decided to change the price while I’ve been here talking to you,” she said. “I’m not mad at any human here talking to me…This just is a glimpse, tangible, provable event that this is happening — because before it was all just hypothetical.”

  Eventually, they “allowed” her to buy the shoes for $3.
