Good price, there are also some 32gb 8th gen for $399.20 but there's barely any stock. They have quite a few models but I'm not familiar with iPad pricing and stock appears limited, so get in if it's a good deal!
Pay with gift cards if you don't want to bother with Afterpay, see the original coupon deal for more info.
Edit: They increased the price from $629 to $661 :(
If having a little more budget
strongly recommend to get the iPad air 4 ($719 on after pay)
Reason below:
- Larger screen (10.9 vs 10.5)
- A14 vs A12 processor [A12 is 2.5 years old]
- Apple pencil gen 2 supported vs gen 1
- Magic keyboard supported
- USB C port vs Lightning port
