Walmart offers the Intex Mega Chill II Floating Cooler, model no. 58821EP, for $13.91. Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from a week ago and the lowest price we could find by $9. It holds up to 72 soda cans with ice and will fit up to a 48-quart cooler. It features six cup holders, four heavy-duty handles, and three air chambers.
