It is a simple sentence
A comma is not required there, but it would make the sentence read better.
Wasn't is singular, weren't is plural. If the subject of the sentence is just one person or object, then use wasn't. If the subject of the sentence is plural, use weren't."Sarah wasn't going to the store.""He wasn't going to the store.""John and Wanda weren't going to the store.""They weren't going to the store."
That does not agree it should be...."Vitamins that are sold in a health food store are not regulated by the food and drug administration."
The pronoun in the sentence is she, a word that takes the place of a singular noun for a female.
The pronoun "them" is an object pronoun. Subject pronouns are able to serve as the subject of a sentence, which in this case would be "they" not them. Example : "They went to the store." (subject pronoun) Example : "I saw them at the store." (object pronoun) The exception to the object rule is when the verb "to be" is used, creating an identity (although this can sound fairly odd if there is no modifying phrase). Example : "It is they who must be accountable." (i.e. They must be accountable.)
during black friday, the lines to get into the store squelched me.
The subject is the one doing the action or what the sentence is about. Examples: She is going to the store. (She is the subject). I am hungry. (I would be the subject). The action that takes place in a sentence is the verb.

Jewish people close the store early on Friday to go to synagogue
Yes, pronouns (in this case, "she") can be used as a subject in a sentence. e.g. She went to the store. "She" is the subject.
John and Mary went to the the store.
No, "The bicycle in front of the store" is a phrase, not a complete sentence because it lacks a subject and a verb to form a complete thought.
The dog barked loudly. She read a book at the park. The sun shines brightly in the sky. I enjoy listening to music. They went hiking in the mountains. He cooked dinner for his family. The flowers bloomed in the garden. We watched a movie at the cinema. The teacher explained the lesson to the students. The car raced down the street.
"Mrs. Smith went to the store." Or: "She went to the store." Never "Mrs. Smith she went to the store." The subject of the sentence is "Mrs. Smith" - if you also have "she" then you have the subject in there twice (if this will help you to remember that you only need one of these).
