>>9977441What do you like? Best to research online and visit online stores. Search for "[insert character, franchse,erc.] figure" and that should get you started.
Don't impulse buy like other anons said. Do thorough research before buying an expensive figure. Also look up an online review of said figure to get a better understanding of what it loks like and how it plays. You might come across one that looks ok and buy it, but then later find a better figure you wish you owned instead.
Use online stores like AmiAmi, Mandarake, HobbyLinkJapan, etc. for searching for Japanese toys. Use online stores like BigBadToyStore and EntertainmentEarth for searching for western toys.
