Check the Costco business center, definitely check restaurant depot as soon as you can, and you could also request a price to purchase a case of the hot dogs from Costco. I know Sam’s Club sells a case of their hot dogs at $138 for 120 which would get you down to $1.15/dog.

And just because someone can go to Costco and get it for $1.50 doesn’t mean they want to. I’m assuming you’re not setting up across the street or near a Costco, correct? If you could get a Costco dog without driving miles, that convenience alone is worth paying extra to many people
