KENNEWICK, Wash. -- The Washington State Department of Agriculture did a study that shows store scanners are often wrong and shoppers end up paying the wrong price.
Most of the time you buy something labeled "on sale". You pay the right amount at least 98% of the time. But a new study conducted by the Washington Weights and Measures Inspectors found that shoppers are more often paying less than the shelf price.
The survey found about 1% of the time, shoppers are over charged. It can range from a few cents to $30. On average, if you over pay it's about $1.96.
The same study says more people are actually undercharged about 1.4% and they're paying an average of $3.96 less than the value.
Mike Louisell with the Washington State Department of Agriculture says, "the Weights and Measures program has inspectors check out nearly 14,000 items and nearly 150 stores. We found there are occasional times when the price charged the consumer does not match what was on the sale price or what was listed on the isle when they picked up the item."
The 150 stores in the survey were all different, ranging from grocery to clothing to department stores.
