Would GMO labeling really increase food prices?

So one of the main arguments against Prop 37 was that if the Proposition passed, the typical California household would see an annual increase of $350 to $400 on their grocery bills. 

This allegation seems rather silly because, honestly, how much would it really cost to add "contains genetically modified corn" on the back of a cereal box?

However, the claim that GMO labeling would increase prices is mostly based on the assumption that many companies would switch to costlier non-GMO ingredients to avoid the GMO labels.

However, it has been noted that companies that exist in both the U.S. and in European countries that do require GMO labeling haven't experienced these predicted price changes as a result of GMO labeling.
