Of course it depends on the advertiser. Sometimes it's very easy to spot a misleading or inaccurate sales description, or a misleading description of associated purchase charges.
I guess persistent offenders are the ones who tend to be highlighted more and, in my opinion, quite rightly too.
Everyone can make genuine mistakes, of course they can. Making persistently similar mistakes is much harder to justfy and one could easily assume it's deliberate.
Well, I think we can both agree they are nothing if not persistent!
