IGBC-certified coolers aren't cheap -- well, most of them aren't anyway. YETI coolers have earned a name for not only being reliable, but very expensive. And they don't go on sale too often either. However, the official YETI eBay store is offering $50 off on its Tundra 65 Hard Cooler. You can grab one for $300 with free shipping until 6/24 when you use code PLAYFUL15 at checkout.
The Tundra 65 features 3" of PermaFrost Insulation and a ColdLock Gasket to keep ice for nearly a week. And it can hold up to 56 pounds of ice or 39 cans of beer using a 2:1 beer to ice ratio. Just keep in mind, the Tundra 65 is no lightweight -- it's 29 pounds when empty. So you might need a buddy to help you haul it around and pound those 39 cans of beer. Or not. Your call.
Update 6/19: As it turns out, this deal extends to other YETI products on eBay, including soft coolers, tumblers, apparel, and cooler accessories.
