OLYMPIA -- Washington state's Department of Agriculture says it's found that some retail store price scanners aren't accurate.
But the agency says it appears shoppers are slightly more likely to be undercharged than overcharged.
The department's Weights and Measures inspectors checked nearly 14,000 items at 148 stores across the state in October and November. They found the scanners were accurate more than 97 percent of the time. But the survey shows consumers are overcharged about 1 percent of the time and undercharged about1.4 percent of the time.
Consumers also came out ahead on prices. The average overcharge was $1.96, while the undercharges averaged $3.11.
