Eggs

Egg cards can be purchased from the lottery once a day. They can be opened any time, and will give you some CD. How much you'll receive depends on how old it is. Older eggs give more CD. The rough estimate for the value of the egg, ~500, doesn't change over time, and will not tell you how much you'll receive by opening it. Additionally, Egg - Enhanced may also be bought from the lottery for 2500, are correspondingly worth ~2500 CD, and provide x2 the amount of CD. After that, There's the Egg - Club, which gives a x3 reward, and is worth 15000. Eggs can sometimes be donated by the courier. Be warned that eggs are a very long term investment. They are easy ways to make money, giving how cheap they are, but not a lot of it. Because the game can be completed in a week, and doing so will make you loads of money, egg cards are mostly a waste of space. The amount you get from them will be completely obsolete by the time they're worth anything. The max an egg can give you is 250000.
