The high priced coolers are nothing more than an imaginary status symbol. They keep ice MARGINALLY longer than a cheap IGLOO and weigh four times as much. When ice gets to $15 a bag, I might consider a marginally better cooler. At two bucks a bag, it just does not make sense.
That's great as long as your near the road, when your 20-50 miles from the nearest store it's kinda hard to just run out and buy more ice. Being able to keep ice for up to 10 days in remote settings is a good thing.
