Aerie by American Eagle offers 10 pairs of Aerie Women's Panties in assorted styles for $30 plus $7 for shipping. (You can mix and match styles; add 10 pairs to your cart to see this price.) That's $3.70 per pair and a savings of at least $10, although we saw this quantity for $6 less last October. Choose from boybriefs, bikinis, thongs, boyshorts, and cheekies.
