Why is Trader Joe's so addictive?

I can't seem to stay away from Trader Joe's, is there something about their products or shopping experience that's particularly addictive? From the delicious snacks to the unique grocery finds, every visit feels like a treasure hunt. But what really keeps me coming back for more? Is it the atmosphere, the prices, or simply the thrill of discovering something new? I'm curious to know what others think might be the driving force behind Trader Joe's addictive charm.
