I have a bait ben - 5 'x 3'- I can hold alot of bunker...... when they die I throw them in the freezer whole in 5 gallon buckets to either grind up for shark chum or use to chunk when there is no bait around. Never thought of as saving money though- sometime it costs me more money in fuel to find the bait, but that is the only way I catch good size bass. I also load up on peanuts for fluke and freeze them tuna chunking- they glisten great on the way down.......
