Retiring & trying to save money

My grandfather is retiring and he is going to have to cut back on a lot of the things he enjoys. He has worked very hard his whole life and is retiring way too late (75). As part of gus retirement gift I'd like to give him a pile if vouchers, coupons, and whatever else companies are willing to send. I know a few companies he really enjoys that I plan to message but I'm looking for more ideas of who I should email. I plan to message Coca-Cola (he has a ton of their merchandise), Walmart (he buys most basic necessities there), and Tyson (he loves their food). It's a short list and I'd like it to be longer, especially since not every company can offer something. I intend to thank the for their time in every email regardless of weather or not they send anything. And I'd like yo thank all of you for taking the time to read and for any suggestions or help you might offer, thank you.
