Never be afraid to tinker. I have some 2-fer wheels I am saving in case of emergency. I also have a box full of 10 cent mechs from the Ford vendor I bought out, I can use them to crap on my neighbor should it come to that. LOL I changed candy to other candy, or chiclets to try to reduce waste. I have also had to say goodbye to locations who were costing more to bad product than they were making in revenue. That is part of the game also. Use toys where you can in trafficked locations, due to COVID this will be case by case, but keep thinking long term, this will not last forever.
I use almost exclusively Ford gum, I was buying a pallet every four months in 2018-19 (my best years ever pretty much) until COVID so I am/was doing some volume. I have some accounts where I changed from gumball to chiclets and had some positive (or at least neutral) results. Meaning, I wasn't throwing out gumballs or more expensive pan candy every service. I have so many candy wheels I had to find some use for them, so I went with Ford Chiclets (w/ 10% Licorice), some of my adult accounts love the licorice and pick them out after they spend a dollar or two getting handfuls of gum out.
