If you're worried about storing the excess from a big bag and don't have a bucket, why not pick up a rubbermaid container while you're at walmart? They're not all that expensive... I buy Oliver's kibble in the giant like 40 pound bag and I just keep it in the bag and put the bag inside a rubbermaid container.... my parents keep a giant container for the dog's kibble too.... they're both kept in an unfinished basement (that often gets water in it with heavy rain) and we have NO problems with either soggyness or bugs... anyway, just a suggestion!
