Aerie by American Eagle offers five pairs of Aerie women's clearance panties for $15 with free shipping. (Add five pairs to your cart to see this price; you can mix and match.) Shipping adds $7, or pad your order with a bra or swimwear item to bag free shipping. That's $4.40 per pair, a savings of up to $48, and the lowest price we could find. (For further comparison, we saw 10 pairs for $35 three weeks ago.) Some exclusions may apply. Choose from boybriefs, bikinis, thongs, boyshorts, and cheekies. Deal ends May 7.
