While looking for a 3-5 gal cooler for my new Anovo Sous Vide cooker, I ran across the 10 and 20 quart Rubbermaid coolers at Home Depot, both priced just under $10. I picked one of each as the 10 qt model is convenient for everyday cooking and the 20 qt model is convenient for larger meals. Of course you can also use them as a regular cooler. Apparently one of the advantages of the 20 qt cooler is that it is tall enough for wine bottles.
Unfortunately this model is no longer being made, so Amazon does not have them in stock for a price comparison. However I did find what appears to be a similar model at Walmart. The 10 qt model was $18.49 and the 20 qt model was $26.79.
