Real-world grammar

Although my major is not linguistic and I am not in a writing profession, I can see that there is a lot of trick in grammar around us; in fact, most of them are the advertisement.

Comment the 1 ad.
Since it is a advertisement, it's main job is to tell you "what the produce(or in fact, the seller) want to tell you in order to persuade you to purchase. The first comma is used to show emphasizes in where the produce from that makes the viewer FEEL its is a good product .The second comma is used to separate the town and the state name.

Comment the 2 ad.
In my opinion, it did not have a really attractive and persuative ad.
However, the aim of this ad. is to attract you to go to the store. It just need to tell you where you should go to get the great deal.

Comment the 3 ad.
It is a hamburger. So,especially in U.S., the more things in the bun, the better. The commas is to separate the ingredients and to make the viewers feels there is a lot of things in the hambuger.

Comment the 4 ad.
In this ad, although the gramme is incorrect, the function of the semicolons, to let the readers have something to expect, did not change.
Aim-Money -----Want to know how----- Method- Trading

Comment the 5 ad.
This one is pretty straight forward. It is telling you the characteristic of their company.What more do you want in a pie? Sweet, creamy and delicous. Because of these three things in their pie, they become a famous company.
