Rebrand your company and the machine’s name to Stockist or My Stockist and market it as “The Vending Machine Re-invented.”
Messaging should be about disrupting/replacing other vending machines, *not people* through a better and more convenient user experience. It’s as easy as grabbing *your* favorite snacks, non-perishables, toiletries, etc from *your own shelf at home* when you’re not home or you temporarily ran out of said item(s). No “exact change only”, slot rejecting crumpled dollar bills, snacks getting stuck on shelf, B5 (your favorite snack ) is empty… It’s not too hard to imagine the short video ads contrasting your experience vs traditional vending machines. Hire Jason Alexander to do the ads.
Donate a percentage of each sale to a local charity such as a food bank.
Promote environmentally friendly packaging and recycling by encouraging or requiring waste and recycling bins next to the machine, or make your own with matching aesthetics.
