Exactly. Be sure of what you're getting. The cheap Igloo 48 qt. "Ice Cube" coolers, for sale at Big Lots, Dollar Store, Target, etc., have ZERO insulation ANYWHERE, plus no drain. $25 might seem pretty cheap until you start looking more closely.
I bought the Rubbermaid / HD 10 gal cylindrical cooler, which is insulated (except for the lid) and has a drain that may be easily removed. The cooler was $40....but something of a bargain. I drilled some holes in the bottom edge of the lid and used the "Great Stuff" spray can insulation to fill the lid.
