I have not had trouble with Menards rebates. Yes you have to wait a while. But eventually I got mine. I used to buy all my materials there when I was in business and I've received many thousands in rebates
Some near a grand each
My club had a culvert that failed and they called the Dnr. While they were waiting for the dnr they replaced the culvert themselves as it was flooding the trail. The Dnr showed up checked their work and told them they did a good job.
