Puma offers up to 60% off plus an extra 20% off select men's, women's, and kid's shoes and clothing during its Martin Luther King Sale, with prices starting at $4.80. (The additional discount is taken in cart.) Plus, all items qualify for free shipping. That beats our mention from three days ago, when we saw the same discounts but with items from $5.60, and it's among the best sales we've seen from Puma in recent months. Sales tax is added where applicable.
