Prospector Zeke, who appears in all the worlds of the spiral, will have some interesting items for you to buy. For a limited time, you can also purchase items from Felix Navidad in the Wizard City Shopping District.
Also, interesting to note that Prospector Zeke usually stocks up on items that are powerful depending on the World he is visiting -- so his Krokotopia stash is going to be better than his Wizard City one, and so on... so be sure and check back with him the first time you hit a new world!
