Thankfully, Wilbur and Orville are addressing a need and adding two new services that collectively comprise Dodo Delivery. When you visit an island using Nook Miles or Harv’s Island, Wilbur will allow you to ship back items to your personal storage on your home island. This frees up the space in your pockets for more items. This is fantastic news for anyone who lands on Scorpion Island, as they’ll be able to fill their pockets with the lucrative arachnids without having to leave behind tools and other items.
You can also “liquidate” your items directly through the Dodo Delivery service if you don’t mind a surcharge. Instead of shipping items home you can sell them to Nook’s Cranny through the service.
However, be warned that if you decide to liquidate, you won’t get the full price for the items you sell. The system works pretty much exactly like the drop box outside Nook’s Cranny. When you liquidate your items, there is a 10 percent reduction in the sale price, and you don’t get the bells immediately. They are instead deposited into your Bank of Nook account the next morning.
