Walmart offers the Suddenly Slim By Catalina Women's Halter 1-Piece Swimsuit in several colors (Red Mini Dot pictured) for $22. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $13 off list and tied with our mention from a month ago as the lowest price we could find. It's available in select sizes from S to XL.

Note: It's also available in plus sizes 1X to 3X for a buck more.
