AZ's has "insane" prices because you/we/I are comparing posted prices to that of AAP, NAPA, CarQuest, rockauto, autoanything, etc.
It's like how once in a blue moon I'll wander into Target, I don't know, just to look around, and see if anything catches my eye; their stores seem to be cleaner, quieter, and the items they sell a bit "higher quality" than other big box retailers (at least in my area).
And of course, I find myself comparing prices of my "typical" stuff that I buy on a daily/weekly/monthly basis....you know.
Target is definitely more relaxed than say Wal-Mart, where there's yelling customers, screaming kids, and snobby kids running all over the place (back when I was a kid, that's what MALLS were for.... lol).
But unfortunately, Target doesn't have much for automotive stuff....they got decents accessories and odds and ends, but no oil, filters, tools, etc. stuff like that.
