Go to Wallmart and get the 5 gallon water bottle , for your wife for cooking , etc . the first one is a little high , but the recycle ticket when you bring back the empty , gives you a new one for only about $5 . and you get it all at once . Sometimes cheaper than a gallon at a time . I also will take other 5 gallon bottles people give me over there , its automated , so nobody knows ………..and get another full one at the lower price . Faster to stock up that way .
