States also are being pretty 
aggressive in looking at things like scanner errors, which you 
mentioned. In fact, the former attorney general of Ohio—well, first of 
all, the current attorney general of Ohio has investigated and fined Dollar General a million dollars
 for scanner violations. Basically, the price someone sees on the shelf 
is not the price they’re being charged by the scanner when they check 
out. The former attorney general of Ohio, a guy named Marc Dann, is now putting together a class action lawsuit against the dollar store chains
 for scanner errors, which he’s estimating Dollar General loan is making
 hundreds of millions of dollars annually in scanner errors because 
they’re so huge and they’re almost always in favor of the company and 
not the consumer.
