Well, since nobody answered my thread, I'll explore on my own!!!
We haven't gone to the store yet, but my host suggested I check out the aptly named "TOOLS"
One thing I saw which I thought was interesting was the way they sell nuts and bolts- the containers have lego-like tops and bottoms, which then match with suitcases you can carry hardware to the jobsite in.
Here's the website- Google Translate does a pretty good job of explaining it!
