Only other place I found this exact model was on eBay for $100 plus shipping:
From WalMart's description:
The Coleman Marine 150-Quart Cooler is a heavy-duty cooler that features a 5-day ice retention and an antimicrobial liner to keep your food sanitary. This Coleman cooler is perfect for cold storage during long camping trips.
Coleman Marine 150-Quart Cooler:
* 5-day ice retention
* Antimicrobial liner
* UV/IR reflective color additive
* Threaded drain with drain valve
* Coleman cooler exterior: 42.4" x 19.0" x 18.6"
* Coleman cooler interior: 35.8" x 13.3" x 13.9"
I found other Coleman 150qt (which for reference is almost 4 feet wide) coolers online for upwards of $100, I'm sure there are differences that make them better somehow, but for big parties, this can't be beat for the price. Holds 223 cans plus 55 lbs of ice. I don't know if I would actually trust it on a boat, being the handles are plastic, but I'd rather have one big cooler like this than a bunch of little coolers sitting around at our BBQ's.
Be gentle....if a receipt scan is requested, I'll post it up.
