Walmart offers the Suddenly Slim by Catalina Women's High-Waisted Bikini in Coral Burn, Black Mini Dot, or Red Mini Dot for $15. Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with our mention from a week ago, $20 off list, and the lowest price we could find. It's available in sizes L or XL, although not in all sizes/color combinations.
