Strange words and phrases

I think, before too long, American English will no longer have the rules scholars and teachers thought it had.  It is played with so often that people will forget what is (or was) technically correct.  

For two days an ad in the Salt Lake Tribune claimed an automobile dealership headline had all their "Suburu's on sale."  

On the radio, a jewelry store is having a "pre-anniversary event."  Does that mean they will have a real anniversary sale later?  Could there be a post anniversary sale?  They can't have a sale without a reason?

A store has several "lighting professionals."  Exactly what is that?  I guess professionals get paid for performance skills, so these people must have lighting skills.  That's different from being proficient or knowledgeable sales people?  Do I need a professional to buy a lamp?

Then there are the clever ways we play with words.  Another dealership was celebrating "Trucktober,"  and a retail store was advertising a "shopportunity."  People just think up these things, but I wonder if youngsters find it at all confusing.  

In a later post, I'll likely carry on about redundancies and--again--the misuse of adjectives as adverbs and nouns as verbs.  I guess I am definitely old school.   I kind of liked the order of the way it used to be.
