The cooler is actually fairly common. I got mine from eBay a few weeks back, and there was 2 of them on their at the same time. I got outbid on one, which was in mint condition, but the 2nd had a Buy-It-Now and I wasn't missing out again - so I grabbed it. The only reason it took me so long to get one was because, due to its size, sellers either wouldn't ship it outside North America, or they were charging an arm & a leg to do so.
Keep an eye on
Kijiji. I've seen dozens of them on there over the past few years.
With the show being shot in Canada, I'd suspect most of their store bought props are from there. I've seen more of the exact green coolers with Canadian sellers than any other location - it's not uncommon for a company to offer products in different colours/features to different regions.
