Unscrupulous stores are bleeding Houston residents dry.

Locals are reporting rampant price-gouging across the flood-battered city — including one store selling bottled water for $99 a case.

The Texas Attorney General’s office says it has received at least 600 complaints about unscrupulous price hikes in the aftermath of Tropical Storm Harvey.

“The majority of these complaints involve price gouging for bottled water, fuel, groceries and shelter,” spokeswoman Kayleigh Lovvorn told The Hill.

Reports include gas stations charging as much as $20 dollars for a gallon, and businesses charging embattled residents almost $100 for a 24-pack of bottled water, she said.

One viral photo showed a Best Buy charging $43 for a case of Dasani — which the chain later claimed was a “huge mistake.”

“Not as an excuse but as an explanation, we don’t typically sell cases of water. The mistake was made when employees priced a case of water using the single-bottle price for each bottle in the case,” a spokesman told CNBC.

Those caught price-gouging face steep penalties — $20,000 or up to $250,000 if the victim is 65 years or older, state Attorney General Ken Paxton told the station.

“These are things you can’t do in Texas. There are significant penalties if you price gouge in a crisis like this,” Paxton said.
