This is about the same price offered by some Ebay sellers for a new, unopened, and unused iPad Mini 2.
However, buying from a reputable store like Staples guarantees your iPad Mini's 1-year warranty will start from the date of purchase.
The iPad Mini 2 is nearly identical to the iPad Mini 3 in every way, except the newer Mini 3 has a fingerprint reader.
Update (2pm EDT):
Staples inventory is regional, so it could be out of stock for some people while in-stock for others.
If out of stock, you can click "pick up today" to check the inventory of your local Staples store.
