PLEASE HELP

I am posting today asking my google friends for help.  My brother is a single dad (widower) with 4 children.  Yesterday he went shopping and for the FIRST time he used coupons and saved $27 he was so excited and he said he new his wife would have been proud.  My request is for any and all advice/ help to get him really couponing to show what he could be saving.  If anyone has any suggestions on what I can do I would rally appreciate it.
