OMAHA, Neb. (AP) — Propane prices in Nebraska, Iowa and much of the country have soared in recent days, leading consumers, retail suppliers and political leaders to ask whether there is more at play than supply and demand.

“I’ve never seen this type of price gouging going on,” said Terry Davis, who owns and operates Country Propane, of Milo, Iowa. “Yes, I call it price gouging. And it’s not coming from the retailers. … It’s coming from upstream someplace.”
