Menards rebate program is great! The thing to remember is that you get your money back in Menards credit, not a check like most other rebates, but I just use it for the next month or two and "recycle" my credit there.
Rebates are offered on all kinds of very practical things, like light bulbs, batteries, extension cords, paint brushes, etc. and are often completely free!
This past month I grabbed these few things pictured here - Windshield wipers, Super glue, and Under the bed shoe organizers. This retails for $28, but I essentially paid nothing.
For more info on their rebate program here's a little "Menards 101".
