Aerie by American Eagle offers 10 pairs of Aerie Women's Panties for $30. Shipping adds $7, or spend $50 or more for free shipping. That's $3.70 per pair and a savings of up to $95. (However, we saw 10 pairs for $35 shipped two weeks ago.) Choose from boybriefs, bikinis, thongs, boyshorts, and cheekies.
