I always do rebates if it makes it worth it, but I also price shop. Nice you can get a rebate from a manufacture and buy it somewhere cheaper to even save more.
I do the menards rebates all the time. They do it to get you back in the store. Never had an issue with getting mine from menards. Even got a couple of missed mailing date sent out.
I remember the days of CD's and DVD's free after rebate or near free. I have some left but not many. some of them $20 and up rebates I spend the $ to track and get signature receipt on them. Had a few pull we never got it, oh really, interesting, I have so and so signed for it at your address.
