They make it hard to find what you want on purpose in hopes you will be distracted and buy other crap along the way. I think it must work on most consumers.
I get that they make it hard to find, so we also buy different stuff. But if I can't find what I'm looking for too often, I won't come back anymore.
Sometimes I really want/need something, and I have all the stores close by. But I still decide to buy it online, and accept waiting a few days, because stores/malls are such a bad experience.
I have the same reaction to it as you.
