For something like that you may want to also consult outdoor specialty stores or even places like the Home Depot or Lowe's. Though they may carry more of that during the spring and summer when they know more people will be outside. But people do enjoy fire in the fall so maybe your Tiki torch fuel is it one of those stores if you don't find it at Walmart.
You would have to look online this is a seasonal item
