bravo in santiago has both milka (formerly german, currently american) and lindt (swiss). i sometimes buy them.
Just checked those Milka in Iberia, they are for Spanish Portuguese and Italian market, while no country of manufacture stated it had addresses in Spain Portugal and Italy printed. So definitely European production and not USA, those that are sold by Iberia.
Iberia as of lately is bringing on many European (mainly Spanish) products and you can find them at reasonable prices... Maybe just slightly higher they would cost in Europe.
They now have whole isles dedicated to these products. Most are under their store brand El D?a. They also have imported Spanish salami and sausages (Argal brand) which are very good and very reasonably priced. And they have agridulce small pickles, I love them... And my daughter is the only Dominican I know that likes them, and she likes them to such extent she eats them as a snack.
