Kohl's offers the Speedo Men's Amplify Stripe Swim Trunks in Mineral Blue or Classic Green for $29.99. Apply coupon codes "JUNEOFFER" and "SWIMWEAR20" to cut them to $19.19. Opt for in-store pickup to dodge the $5.95 shipping fee. That's the lowest price we could find by $8. They're available in sizes S to XL. Deal ends June 30.
