A bunch of kindles?
unless the kindle has gotten very good at Portuguese, and unless Amazon has gotten very good at furnishing ebooks in Portuguese, that's a truly insulting offer.
The Amazon Brazil ebook toplist makes me think "insulting." ebook selection even in Spanish is weak, and that's despite the large numbers of Spanish readers in Amazon's home market.
If Amazon wants the domain, they needn't sweeten the pot - they need a much bigger pot.
A no-strings goodwill offer to help rebuild the museum which recently burned might be a good start.
