Season ticket holders will be able to see the Carling Cup quarter-final with Manchester United on Tuesday 30 November for just £15 for adults and £5 for kids.
The cut-price seats are the third time the club has slashed prices during this season's cup adventure at the Boleyn Ground with the owners determined to reward fans for their loyalty. The home second and fourth-round ties with Oxford United and Stoke City also saw massive seat savings passed on to supporters.
As before, non-season ticket holders will also benefit from the significant reduction with prices set at £20 for adults and £10 for kids for a mouth-watering match that will take the winners to just one tie from Wembley and February's showpiece final.

Chairman David Sullivan said: "With the promotions we are also running for West Brom, I am delighted Manchester United have agreed to our pricing policy for the cup. Everyone is looking forward to what should be a special night under the lights.
"This is another chance for us to give something back to the supporters for their fantastic support. We know how important each and every one of our fans will be in what is going to be a big month for the club."
The selling dates have been set as follows:
Season ticket holders - Wednesday 3 November to Thursday 11 November
Club members - Friday 12 to Monday 15 November
Cup ticket history and West Brom priority* - Tuesday 16 November (personal callers, telephone and postal only)
General sale - Wednesday 17 November onwards
* After season ticket holders and members, there will be an exclusive selling period for anyone who has proof of purchase from the Oxford and Stoke City cup games - with those attending West Bromwich Albion on 10 November also given access to this guaranteed priority period before general sale.
To be eligible for the West Brom offer, fans must book in advance and retain their ticket stub - while anyone buying multiple tickets should supply the names for each seat. This priority chance for the cup will not apply to anyone paying on the day on 10 November and cannot be used in conjunction with any other offer.
All offers are subject to availability and tickets are also selling fast for the arrival of the Barclays Premier League's surprise package this season, so anyone interested in being at the Boleyn for either game should move fast or face disappointment.
