Tanga offers this Beer and Soda 6-Pack Belt Holster in Camo or Black for $3.99 plus $2.99 for shipping. (GearXS via eBay charges a penny more.) That's tied with our May mention as the lowest total price we've seen for any beer belt. (It's also a current price low by $12.) It holds six bottles or cans of your favorite drink (be it alcoholic or not) and fits waist sizes from 30" to 54".
