Amazon offers its AmazonBasics Microfiber Cleaning Cloth 24-Pack, model no. CW190423, for $9.88. Check out via Subscribe & Save to drop them to $8.40. With free shipping, that's $3 under our January mention and the lowest price we've seen. (It's also a buck under what you'd expect to pay for a similar 24-pack at a local store.) These 12x16" cloths purportedly absorb eight times their own weight.
