One interesting and also really annoying phenomenon about going to another country is that it can be really difficult to find what you want to eat in the grocery store. I think the grocery stores in each country have to categorize and organize goods by how people use them, which differs in each country, and when you mix that in with goods actually missing, the experience can be really frustrating. It is not unusual for ex-pats to swear that something is not sold in the country, only to find out that they were looking in the wrong section. For example, in Germany I've known ex-pats to complain that there is no sweetened condensed milk, but I found it at Rewe next to the coffee (do Germans put it in coffee? Sounds good, I guess). At Rewe the peanut butter is next to the jelly, where I would expect it, but at Real it's in the "American foods" section :D
I would expect any store that sells yoghurt in the US to have non-sweetened yoghurt, too. Just keep looking :) Dairy products are also sorted differently in each country.
