You can find the list of e-books you've purchased in your account, under My Library. Once the payment is confirmed via email, which may take one to two (1 to 2) business days, you can download your e-books. The status of your order payments, whether pending or confirmed, is reflected under the My Orders tab in your account.
For print books:
Delivery for print books may take 1-3 working days after confirmation for major cities in the Philippines, and 2-5 working days for provincial deliveries. For international orders, it will take 5-7 working days. Orders made during the weekends or on a holiday will be processed the next working day.
You also have the option, in the checkout process, to pick up your books at the Press bookstore in the Ateneo de Manila University campus.
