I have been looking and honestly, the cheapest place I have found is to buy them direct from S'well. We had one last year for our trip and it does everything they say it does. We took water with ice into the park and at noon there was still ice in the bottle. I unfortunately left the bottle in the door of the rental car when we got to the airport, but it was the best thing we ever bought for a trip to Disney. We are going to the Caribbean in February and we will have one for each of us. I can't day enough good things about those bottles.
