Hi there Jake! Good evening! Here are your corrections. ^_^

Many people like to go shopping, but I don’t enjoy shopping because shopping makes me tired. I have to walk around the department store to find something like shoes or clothes. Also, I need to check the price to find out which is cheaper. It is boring. My mom usually buy something for me. She works at a department store. Therefore, she can buy something at a cheap price. I don’t need to care about bargain sales. I just choose whether I will take it, or not. She have a good sense about choosing stuffs. So, I mostly agree with her. Instead of shopping, I just spend my money on buying books. I’m happy when I see my book shelves with a lot of books. I like reading books. I often buy books on the internet. After paying, the site gives me some points that I can use when I want to buy books. Also, it gives me some discounts. If I order books before 11 AM, I can mostly take the books until that night. The delivery fee is free! It is very comfortable and advantageous.
