Police say they carefully target cashiers to carry out their crimes.
Two women hitting Walmart stores to steal gift cards.
Now, police are offering a reward in hopes of finding the thieves behind the scam.
Police say the women are running scams at Walmart stores across the state.
They hit a Walmart Fresh Market store on Saron Drive in March.
"They approached the cash register with a pre-paid cell phone and $4,000 in unactivated gift cards," Detective Jeremiah Davis of Lexington Police said.
Police say the women pretend to swipe cards, and somehow talk the cashier into running the transaction as cash, after the card doesn't register.
"You see one lady reach behind the cash register, showing the lady (cashier) which buttons to push to activate it as a cash sale," Davis said.
The women have made off with $4,000 worth of activated gift cards, and the phone.
They've also hit the Walmart in the Palomar Center, and a Walmart in western Kentucky as well.
Crime Stoppers is offering a $1,000 cash reward for information leading to an arrest in this case.
