We have all heard of price wars in the energy industry which are most commonly associated with gas stations. But, the propane industry is much of the same.

But in Delta, at least one retailer says it has gone too far.

"We're taking a loss just trying to compete with them because all they want to do is take my business," Teresa Grego, owner of the Valley Sunset RV Park said.

According to Grego, the problem stems from a business relationship gone bad. A once profitable four-year agreement went sour when she and propane distributor Ferrellgas had a falling out.

After she terminated their contract and went with a different company, the distributor started undercutting her prices and now she is convinced it's all in an effort to force her out of the industry.

"No matter what price I put out, they keep going under," Grego said. "You know what they're doing, I mean it's obvious."

Making matters worse, Ferrellgas' Delta location is literally right next door to the RV park, so the battle continues every day.

"I cannot compete with Ferrell on price, hands down, because I have a middle man and they don't."

Driving around the city, KJCT News 8 found propane prices between about $2.00 and $3.00 per gallon which equals a modest markup for most retailers over cost.

But in Grego's case, she says she's being forced to sell well below cost at a $1.39 if she wants to stay in the business.

"They are doing it just to put us out of business and take my customers because I fired them."

According to pictures taken by Grego and shared with KJCT News 8, Ferrellgas has dropped its price from $1.35 per gallon to $1.00 in less than two weeks. Grego's has followed in that direction.

Our in-person contact and phone calls with Ferrellgas employees went unanswered, so we checked state law and found nothing regulating the price of propane prices.

Still, Grego says what Ferrell is doing is just plain wrong and purely unethical.

"The minute I would shut down, it wouldn't be a dollar a gallon. It would be two to three dollars a gallon."
