Amazon's supply method wasn't technically sophisticated because it didn't have a warehouse, which meant no inventory at all.
After customers placed orders for books on the website, Amazon would then purchase the books from major book wholesalers like Ingram, receive the books a few days later, and then dispatch them to customers.
Thus, it could take as short a time as one week or as long as one month for a book to arrive in the reader's hands.
But in that era, for the sparsely populated expanse of America and book lovers around the world,
having one's beloved books delivered to their doorstep after only a week was an incredibly delightful and reassuring ordeal.
After Amazon went online, its reputation began to spread quickly due to word of mouth from its earliest users.
At first, every order would excite Bezos and his employees immensely.
