When I went to Mexico they seemed to only have generic amiibo.
I went to a LOT of stores to go amiibo hunting, and these were my results.
Chetumal, Quintana Roo, Mexico
Liverpool
* Mario, ALOT of Mario
* Donkey Kong, ALOT Of DK
* Bowser, ALOT of Bowser
* Toon Link (2 left)
* Shiek (2 left)
* Diddy Kong
Game Rush by Blockbuster
NONE, probably because I bought the last Toon Link and Shiek the last time I went.
Walmart
NONE! I don't even think they stock amiibo since they have Mario Kart DS for sale still, and it costs MORE than Mario Kart 7.
Sam's Club
* Peach
Cancun, Yucatan, Mexico
The amiibo supplies were more plentiful here, but still only common trash

None, but I think they had DK, Mario, and Peach on pre-order or something. They were one a shelf near the cashier.
In other words, it seems Mexico has only crappy amiibo.
Belize, where I live, doesn't even sell amiibo. Wait.. they do... but at scalper prices. One store sells one, and I think they sell common trash for like $80 BZD, which is $40 USD.
