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.
Buying protein in bulk saves a lot over the supplement store.
I buy iPhones. I’m not sure they’re overpriced but they sure are pricey.
