There are a few ways to get NC Gift Boxes. NC Gift Boxes are automatically deposited into your Inventory when you redeem a Neocash Card (just like Limited Edition Bonus Items). You can redeem your Neocash Card(s) in the NC Mall to receive your NC Gift Boxes. However, NC Gift Boxes can only be used to gift NC Mall Neocash items to other Neopets users.
The number of Gift Boxes you receive is determined by the denomination of the Neocash Card redeemed:
A $5 Card will grant your account 1 NC Gift Box
A $10 Card will grant your account 2 NC Gift Boxes
A $15 Card will grant your account 3 NC Gift Boxes
A $25 Card will grant your account 5 NC Gift Boxes
Directly purchasing Neocash, will also grant you Gift Boxes. You can also directly purchase NC Gift Boxes from the NC Mall.
You can also get NC Gift Boxes for free! Playing Trudie’s Surprise will give you a chance at getting a Gift Box. Occasionally, NC Gift Boxes are also given out for free through Gift Box Capsules, so keep an eye out for when those are released!
