It's got nothing to do with the club anymore, unfortunately. The club shop is a franchise run by Just Sport. They make the decision on what is sold in the shop and they have had the Scarves made. Some people may not like the idea but there are plenty of Barnsley fans that will buy these Scarfs. It's a matter of personal choice.
What do these scarfs look like? I paid £70 for a Pretty Green scarf so I don't mind paying stupid money for a scarf haha!
