Menards is not normally a place I would have thought to coupon, however it has yielded better deals on some items than I have found at my local grocery stores. They also have a lot of things cheap or even free after MIR that you can not find coupons for.
Menards sales typically run for two weeks from Sunday to Sunday, so almost every Sunday there are 3 active sales.
Menards MIR are available in the form of a Menards Rebate Check (store credit), similar to RR and ECB’s. Once you spend a little out of pocket you can continue to roll them for additional Free after MIR items or save them up for projects you’re working on.
