NEW YORK -- What started out as a love letter to fans of an adored time-travel classic may end up being a sore spot for PepsI.
The company appears to have quickly sold out of "Pepsi Perfect," its homage to "Back to the Future," leaving legions of fans disappointed.
Pepsi said it would release 6,500 bottles of Pepsi Perfect to fans in the U.S. on Tuesday evening.
But some fans said they were unable to buy the soda, leading to outrage on social media.
The soda was featured in the 1989 film "Back to the Future Part 2," a story that transported characters Marty McFly and Dr. Emmet Brown to Oct. 21, 2015.
The collectible "Pepsi Perfect" was selling for $20.15, to commemorate the year 2015, and featured the same 16.9 ounce bottle that McFly orders at Hill Valley's futuristic "Café 80's."
Some reviewers on Amazon, which also sold the beverage, were unhappy with the situation.
"Not happy with the release," wrote reviewer JacquelineS. "What's the point in all the hype just to disappoint customers and fans?"
"Stayed up hoping I could snag one at MIDNIGHT...even after following them on twitter and trying every link....seems like these were sold out before anyone could actually buy them..very disappointing. Looks like I will continue to NOT drink pepsi," wrote reviewer Tyler.
After receiving many negative comments, Pepsi released a statement on their Twitter page saying Pepsi Perfect has not sold out.
"The future may have arrived early for some lucky fans, but #PepsiPerfect isn't sold out just yet! It goes on sale this morning," the statement read on Twitter.
