Walmart discounts a selection of women's swimwear, with prices starting from $3. (Prices are as marked.) Opt for in-store pickup to dodge the $4.97 shipping fee or get free shipping on orders of $50 or more. A couple of best bets, both available for pickup:

• 100 Degrees Women's Trax Rash Guard Swimsuit Cover-Up for $18 ($5 off)
• Suddenly Slim By Catalina Women's Retro Slimming 1-Piece Swimsuit for $25 (pictured, $10 off)
