I love what you are doing. I bet if more people realized that you are doing this, they would gladly donate more money and possibly donuts, food, and drinks. We have a hot chocolate maker, Stephens Gourmet, based right in Farmington, who not only had delicious hot chocolate and apple cider, but is also great about working with local opportunities.
I contacted them, when I was on a feeding tube for 5 years, but was allowed to sip on a few drinks. Their Carmel apple cider was one of the few things that didn’t trigger my Crohn’s or Gastroparesis, and soothed my throat from hanging the NJ tube and pump pumping 24/7, but that product was hard to find out of season. I sent them an email to see about buying in bulk, and not only did they give me a vendor discount on bulk, they gave me a ton of vouchers to get it free at any grocery store.
I was only looking to buy in bulk, and they went out of their way to do something so kind for a nobody like me. I bet if you offered to advertise by wearing a shirt or put something on social media, they would give you a deal on hot chocolate and apple cider. There are also other local donut vendors who would probably love to get that publicity, while BYU is winning and in the national and local media. I am not as familiar with Provo, but Lee’s grocery store makes delicious donuts, as does Rocky Mountain donuts in Ogden. Heck, you could even talk to them about the NIL deals and maybe get a few players involved.
