Many shoppers will use price-comparison web sites before making a purchase online.
But Texas Attorney General Greg Abbott has a warning about those sites.
He says several "price-comparison" web sites are unlawfully misleading online shoppers.
"These companies we are suing promise independent, reliable and trust worthy comparison price information. What we uncovered was a cash for ratings scheme," said Abbott.
Some of the sites in the lawsuit include shopcartusa.com, Didyouprice.com, Flyingprices.com and digitalsaver.com.
