Aerie by American Eagle offers 10 pairs of Aerie Women's Panties for $30 plus $7 for shipping. (Add 10 pairs to your cart to see this price.) That's $3.70 per pair and a savings of up to $95, although we saw the same offer for $2 less last week. Choose from boybriefs, bikinis, thongs, boyshorts, and cheekies.
