Do we can use will with I in any sentence instead of using shall ?

Which of the following sentence are correct
Example ....
I shall go there.....I will go there.
I will read it...........I will buy this shop.

Dear Student,
Will and Shall, both can be used with I.
The differences between the use of Will and Shall are:
- I will- can suggest an intention, or a probability of future action, whereas I shall- suggests that the future action is must and certainly be done.
- There is a difference of degree of courtesy for both the verb forms. "I shall: signifies higher courtesy. 
- The use of "I shall" is considered traditional and at many places, it has been replaced with "I will". 

Hope this clears your doubts regarding this topic.
