Mark,Adam,Dagny... thanks...I've used frozen 2L and gallon jugs (typically)for hurricane outages, but since retirement, have a lot of left overs, and my concern was that I couldn't get larger solid blocks in the filled cooler....I use one for the non frozen perishables like lunch meats etc...other for solid frozen stores....I'll check out the discount stores, as I typically don't shop there... again thanks,
