GoSport & GoPong via Amazon offers Prime members its GoPong Sunscreen Alcohol Flask 2-Pack for $6.99 with free shipping. (Non-members can qualify for free shipping with orders of $35 or more; otherwise, shipping adds $6.14.) That's tied with our mention from last fall as the lowest total price we've seen. (It's a current low by $7.) Each of these incognito flasks holds 8 oz. of alcohol.
