Just discovered this. A company named Juguete Cremino that makes chocolate has had DBZ figures that come with the chocolate. It's kind of like how we have (had?) toys that came in cereal boxes in the US.
I've only seen most of them on Mercado Libre, and you have to select the country you want like Peru, or Argentina, and then search. The only problem is, Paypal isn't used on there, and you can only pay with a bank account that is one of the South American-only banks.
Other than that... an advanced search on ebay, and select items only located in Peru.
