Amazon offers its Prime members the Seavenger Snorkel Set in 5 colors (Black Silicon pictured) for $28.99 with free shipping. (Non-members can spend $35 to bag free shipping; otherwise, it adds $6.98.) That's the lowest total price we could find by $6. It includes a dry top snorkel, trek fin, single-lens mask, and gear bag. It's available in sizes S/M or L/XL.
