Personally, I buy protein powder even though I know the ingredients are actually too cheap to justify the price. But I’m too lazy, and the reward of a cold chocolate shake after working out makes me forget about the outrageous cost. It’s a little guilty pleasure I’ve come to terms with.
An iPhone. I’ve tried Android 3 separate times, a Nexus 5, 6P, and Pixel 3A XL, and I keep crawling back to pay the Apple tax.
Although the accessibility features have replaced several assistive devices that each cost several times the price of the iPhone, so it’s a matter of perspective.
