The Potters want to see a full allocation of 6,000 fans in Anfield to cheer on City to what could be a famous victory.
The club are entitled to 45% of the ticket money from the quarter final tie with Liverpool, but they have waived that and passed the savings onto the fans who can now see their heroes at the Famous Anfield Stadium for just £20.
It’s just like beer being on a rollback at Asda, only better!
The trip to Merseyside marks the third successive season the Potters have made the last eight of the competition and keeps them on track for a return to Wembley for the Semi finals and the Final.
"As we stated when announcing a season ticket price freeze, we want to keep top level football as affordable as possible and we recognise that our supporters have committed to a considerable amount of expense over the last year,"Tony Scholes told the club's official website.
"It would be wonderful to think we could get back to Wembley again and we believe this offer is a cost worth bearing to give us every chance of achieving that aim.
"It helps our fans and, in turn, we know they will help the team by giving them fantastic support.
"Our players will get a tremendous lift when they see the entire lower tier of the Anfield Road Stand filled with 6,000 fans, helping to create a great atmosphere."
