I have to confess that, in small doses (so as not to lose my sanity), I sort of enjoy the all-sorts-of-random-crap stores. I could spend unhealthy amounts of my time in those 100 Yen stores (or whatever they are called, I might be misremembering their names).
But Don Quijote was just garish and uncomfortable. It was even difficult to walk the aisles. Everything about it screamed to me "get out of here fast!". I can't understand how it is successful.
PS: while on the subject of these crap/budget stores, can someone from the US tell me if my hunch is right about the following? While visiting the US I discovered those Five Below stores (everything between $1 and $5) and I think I figured their trick: while the advertised price range is true, this doesn't mean what they sell is actually cheap! For example, I'm pretty sure I saw Hot Wheels cars at about $3 when everywhere else the same toys were near $1. Am I missing something?
