Understanding availability:

• Availability = time it takes for a book to be ready to ship
• For out-of-stock items, we need to order from the publisher first

Calculating delivery time:

• Total wait time = Availability + Shipping time
• Example: 5-day availability + 2-day shipping = 7 days total

Good to know:

• Availability times are set by publishers, not us
• These are estimates, not guarantees
• Even digital items may have availability periods
