Get 30 generic Magic Erasers for $3.50

I've written about melamine foam (sold as Magic Erasers) before. They are great for getting rid of mars and stains on almost any surface. The last time I reviewed them, a box of 30 cost $7.89 on Amazon, which was a great price. Today I learned that the price has dropped to $3.49 for 30.https://youtu.be/VkBSlD60rDA
