What's a good value everyday item you've bought?

The most overpriced thing I've ever bought was a speaker for my mom, 1500 bucks. My mom loves square dancing, and someone gave her a speaker that she pulls out to the countryside and uses when she goes back to the countryside. The speaker had a bad battery, it had to be plugged in all the time and would constantly remind her to charge it. I bought her a speaker, my mom has been complaining why buy so expensive ah, that old speaker you help me change the battery on it, it is not a waste of money. But I can see that she is actually very happy. Every time I go back to the countryside, she and my father either open the speaker to sing, or square dance music. I will accompany them to sing, my daughter-in-law accompanied her square dance.
