No, but that's easy not having a car.

Where do you shop for occasional items?  

Depends on how much time (and nerves) I have. Usually what is nearest -- can be a mall, can be a big store, can be a small shop. If I look for something specific or rare, I go to all places I know.

Where do you not?  

Nothing is pre-excluded, but I mostly avoid brand shops, and (like you) 'trendy' shops with blaring music. Generally, I don't like to shop (maybe it's a male thing?), and dislike for flashy but crappy products at large stores is paired with dislike for pushy small-shop owners who won't let me examine their products in peace.

How often do you buy items that you find are poor quality and have to buy again?  

Relative to what? I generally try to buy quality over low prize, because my experience is that on the long run this is the cheaper option, but I don't always know in advance what's quality and what's not.

How much e-shopping do you do?  

Near zero. If my memory doesn't trick me, my current PC was the first and only, and that was a bad experience (they didn't sent it as ordered, and sent it with faulty parts).
