Frederick's of Hollywood offers seven pairs of select Frederick's of Hollywood Women's Panties (Valerie Lace & Satin Keyhole Bikini in Black/Red pictured) for $24.99. Shipping adds $5.95, or spend $50 or more to bag free shipping. That's $3.57 per pair, a savings of at least $31, and the lowest total price we could find, although we saw this same deal for $6 less last week. They're available in sizes XS to XL, although not in all size/style combinations.
Before you send in your tax return, double-check that you haven't made one of these mistakes that can trigger IRS scrutiny.
