When Luffy went to sea, he spent no money. After meeting Zoro, the mother and daughter invited her to a meal at a restaurant in the town. Later, I met Nami and Bucky in a small town, and Nami treated Luffy to a meal. A meal from Usopp. At this time, Nami had just stolen Bucky's treasure and was not short of money. At the sea restaurant, you should have spent your own private money when eating. Zoro Usopp had not long since boarded the ship, and he still had some savings. After arriving in Rogge Town, Zoro ran out of money and asked Nami to borrow money. Nami didn't spend any money because of Sanji's care. Luffy, on the other hand, has absolutely no money. There was no shopping in Nami's hometown, so a group of people beat Aaron away and left. Before leaving, Nami stole many people's wallets, which were Nami's savings. When they arrived in Rogge Town, Nami had savings, but Zoro had no money, so he borrowed money from Nami to buy the knife. Usopp and Sanji should have some money left to purchase some things. Luffy never had much money...after entering the Grand Line. When I met Rab, I didn’t spend any money. Then they went to Whiskey Peak and were entertained. In the end, not only did Nami spend no money, she also stole some treasure, although she said the treasure was very small. Next is the small garden. There is no place to spend money on Taikoo Island. I did purchase some things when I was in Alabasta, probably using the money Nami had stolen or her previous savings. When they arrived in Gaya, Robin went to investigate alone. At this time, Robin had just boarded the ship. Judging from the treasure she had given Nami before, she should have some savings and spent her own money. As for Nami and the others' expenses in the town, it's not like they just collected the gems. Being wealthy, they can still afford cherry pie and wine. As for Kong Dao... he was sent directly to sanctions... without buying anything. After the battle, Usopp exchanged items for a lot of shells, and the last group of people left with a lot of treasures.
