Neopets: Island Builders
Crystal Negg Store
Crystal Negg's are the Island Builders version of Neocash, a premium currency that can be purchased for real money in exchange for virtual items. Crystal Neggs can be earned in small amounts by completing Active Quests, but otherwise must be purchased in the game's Crystal Negg Store. Currently you can access the store in two ways, and it will look different and have different functionality depending on which method you use. You can access the default Store view by tapping the Crystal Negg counter at the top of the screen.
This will load a menu with tabs and packs that are on sale. However, tapping on the Premium Emporium building (once it is built) will load a different menu with King Crabby sitting at a desk. Tapping on the book on the left of the desk will load the default store view, while tapping the Crystal Negg on the right side will load otherwise inaccessible limited time deals.
Welcome Pack
All users are offered a free pack of decoration items when they visit the store. This can only be claimed once per game, and contains items that are craftable for free in the Antiquity-Fixity.

Contains: 30x Rope Fence, 8x Rope Fence Corner, 4x Wood Gate, 1x Fountain Spring, 2x Driftwood Bench, 3x Hanging Lantern, 10x Dirt Path Tile, 10x Wood Path Tile, 40x Stone Path Tile, 8x Leafy Tree
Cost: Free
Negg Packs
Crystal Neggs can be used to instantly complete gathering and building jobs on the island. The longer the job is set to take, the more Crystal Neggs you will need to spend to complete it.
These are the packs of Crystal Neggs currently available.

Note that the price of these Crystal Packs will be shown in your local currency and as such can vary across the world.
Decoration Item Packs
In addition, you can buy some items for your town in the Crystal Negg Store. Currently, there are multiple packs available across several themes. Some of the items in the packs can be crafted normally without spending real money, but it is currently unknown if that is the case for all of them.

Customisation Item Packs
The Crystal Negg Store also offers packs of customisation items in the form of basic versions of Hats, Paint Brushes, and Paint Rollers, which can be combined with other non-paid items to make usable items. Currently, buying the basic packs from the Crystal Negg Store is the only reliable method of accessing them in the Android version. They cannot be crafted for free any longer. However, they are rarely available via daily login bonuses.
(Although they are awarded as Wheel of Offers items, the Wheel of Offers itself does not reliably grant the items it claims to currently.)

Food Packs
The Crystal Negg Store offers packs of food items that can be fed to your pet to instantly refill both their hunger and happiness, unlike regular food items (Omelettes), that only refill hunger. They are stored in a distinct part of your inventory away from Omelettes, and are also fed to citizens through a different section of the customisation menu.

Limited Time Offers
Tapping the large Crystal Negg on the right of the desk will load a new screen with three limited time offers that rotate daily. Each of these deals will offer a reduction in price over the usual Crystal Negg cost. Individual items can appear this way, as well as packs as a whole (though sometimes the exact contents of these packs can be different from what is normally gained by purchasing them). Additionally, the deals section of the store can sometimes list items that are otherwise unavailable in other parts of the store.
Previously, other limited time offers appeared in the regular store offerings. It is unknown if these deals will be returning with the addition of a dedicated area for them. At present, only one pack has been released this way, and contained an exclusive building and Neopet. The Neopet species is currently not available outside of the cash shop: the Kacheek.
Unlike regular packs, these offers can only be purchased directly with real money, and not via Crystal Neggs themselves.

Contains: Library Blueprint x1, Kacheek Neopet Unlock x1, 2x Veggie Garden, 1x Garden Rack, 1x Tomato Garden, 1x Clothesline, 5x Cypress Tree, 5x Cafe Fence, 1x Square Mailbox, 1x Trash Can, 3x Ghost Paint Brush, 3x Plushie Paint Brush, 320x Crystal Negg
Cost: $6.99 (Or local equivalent)
Subscription
During early beta, the Crystal Negg store also advertised a subscription feature, similar to Premium on the main site. For a monthly fee, users could gain access to exclusive quests, free Crystal Neggs, and exclusive Neopet citizens for their town (implied to be a Uni).
This subscription feature was never actually live and was removed as an advertisement with a late build version. It is unknown if it will be offered again in the future when the app reaches official launch.
