She bought $480 in electronic-purchase cards — $280 from Dollar General and $200 from Walgreens.
Police plan to release the video to Crime Stoppers of the Quad-Cities, said Johnson, who advises people to examine $20 bills.
If Milan has had two or three incidents, other nearby cities probably have, too, he said.
"When you see these kinds of cases, they bounce around around a little bit," Johnson said.
