Derby travel to Oakwell for their last game of 2013 on Sunday 29th December and their supporters will pay £15 adults, £10 concessions with a £5 charge for under 12s.
The return game will be played on Easter Monday when Barnsley fans will receive a similar welcome at Derby with charges of £15 adults and £10 concessions.
Explaining the decision, Barnsley chief exec Ben Mansford said: "When Sam (Rush, chief exec at Derby) and I met at a recent Football League meeting we discussed that our respective fixtures fell at family times, Christmas for the match at Oakwell and Easter Monday for the match at Derby.
"Given our respective superb away followings it was a unique opportunity to give our supporters reduced ticket prices at such financially restrictive times. To add to this our fans have had to endure, and will still have to face, some quite ridiculous midweek away trips as well as a Friday night at Ipswich. I am delighted that we have been able to, in collaboration with Derby, offer these prices.
"With our away fixture at Derby coming in the final fortnight of the season it will be a key game for us and this initiative means many more fans will be able to come and support Barnsley at the iPro Stadium."
In response, Derby's Sam Rush said: "We're delighted to announce this reciprocal agreement with Barnsley and hope it will be a big hit with our fans. We have a magnificent away support and our travelling army have been turning out in huge numbers to really spur the team on.
"Hopefully we will see another large turnout at Oakwell as a result of this offer, especially as it is only an hour or so up the road, in what will be a key Christmas gave for the side."
Rush added: "I know Ben Mansford very well and I would like to thank him and Barnsley for being so open to what is a great initiative to benefit both sets of supporters in following their team away from home."
In a season where Burnley fans have had to pay considerably more than £30 on two occasions to watch the Clarets away from home, and when one set of away supporters have been charged in excess of £30 to sit in the cricket field stand, this is positive news.
It is an initiative that has been taken up by a number of Premier League clubs but this is the first news I'm aware of when two Championship clubs have come together to make such an arrangement for their travelling supporters.
Well done to both Barnsley and Derby and let's hope we hear much more of this in our league as clubs surely have to start making more sensible decisions with pricing.
