I ordered my algebra book from Amazon.com because I could get a new book for the same price as a used book would be at the college bookstore, and I wouldn't have to pay for shipping. So I ordered it. And I waited.
I also ordered some birthday gifts for my niece, and they arrived at her house. My book still said it was in transit. I was waiting.
My class started on Tuesday. No book. Wednesday. No book. I told Amazon to send tracking status to my phone, which never happened. Probably because I did something wrong, rather tham because they did something wrong.
Saturday morning, I saw that the book had arrived at the post office in my town, but it didn't say "departure scan" at any point in the day.
I checked the college library to make sure they had the book because I have homework due on Tuesday, and I really needed the book.
I freaked out, and finally just went down to the library, got the book, and did my homework.
And I got home, and my book was on the porch.
Better safe than sorry?
