If the title availability says "On Our Shelves Now" the title is on hand in the store (unless we just sold it). We will contact you if it needs to be ordered.
"Usually ships in 1-5 day"  is not on hand in the store and will arrive in 2-5 business days. 
"Backorder" is a moving target. Backordered items can take 5-25 business days. 
"Special Order", "Out of Print", "Hard to Find" means it is not currently available to order.

When searching for titles, you can sort by what is "in stock" and see which books are currently on our shelves.
