My recommendations is to make friends in Europe and swap cool stuff. They send you Ritter Sport and you send something they desire in exchange. Bars like this on sale will often sell for Euro .59 in all kinds of super markets.
Rum Raisin might not come here easily because of the alcohol implications, but you are right, it is delicious.
A parcel from Germany to the USA is 16,90 Euro (weight limit 2 kg).
So who wants Ritter Sport or Milka (the better chocolate) or world famous Lebkuchen from Nuremberg and will send me something I want from the USA?
