To be fair, Hearts are doing their best to promote it and galvanise their support. Aberdeen in comparison are doing very little to push semi-final sales.
Hearts have posted as much about their semi sales this morning as Aberdeen have in a week. They're now up to 19,000 and have asked for more. Meanwhile no-one really knows what Aberdeen have sold and it's been up to fans to try and work it out themselves.
It's almost like Aberdeen are in a huff over the venue and kick-off time. I get it, I wouldn't be trying to shame anyway into going, but at least try and generate some interest from your support.
