Digging:
-Add some cheap crab repellent. :/
Like $35 a can and lasts for 10 minutes.
-Chest/Buried treasure
This is a rare chest you can find and it's sold for lots of money. Chances of digging one up is 1/2850.(Idk why,just seems reasonable.) And each chest contains 50 random types of coins.
Gold coin-$500
Silver coin-$300
Copper coin-$100
So if you get one,you get at least $5k if your luck is so bad that you get all bronze coins. But if you get all gold coins(which is close to impossible),you can get $25k.
And yes,these chest are tradable. Like trading away some gifts and they won't know what's in it unless they open. Also,you can't open it,sell the coins and then trade the chest lol.
Pizza:
Every 350 pizzas you make,you get a coupon that can be used once. Every 10 pizzas you buy,you get $10 off. So I forgot the price of pizza,so imma say $5 each. $5*50(pizzas)=$250-50(coupon)=$200.
This is just an idea.
Lastly,Trash Picking:
While Trash picking,you can also find these items.
Banana peels-$7
Soda cans-$3
Bags-$8
These also come with an achievement.
-Collect 50 banana peels(DK's hustling)
-50 soda cans(Can lover)
-50 bags(Grocery shop worker)
