How to keep costs down for disposable products

In the US, there is basically no reimbursement for disposable absorbent incontinence products. Our senior citizens, who are on a fixed income, are really hainge a difficult time purchasing products, and are always looking for sources of free products - or at least at a greatly reduced cost. Other than a few diaper banks, there is very little that seems to be of help! I would love to hear of ideas that people have used to help keep the costs down, or of resources they have used that have helped. Or any ideas, suggestions, etc. Thanks!!
