In 2016 I submitted my rooftop whole house fan to a major idea buyer for their work to get my idea out to the 22 big box stores they said they work with. Those stores are shown below. I called several of the personally and got to know key purchasing personnel in each. I was successful with Tractor Supply – they offered me a contract to place test sales in two stores in 2019.
I can gurantee you that if you hire me to review your idea and it fits with Tractor I can get them to look at it.
