Er ...yes, but it's much less hassle just to get the same warm fuzzy feeling by lending the ticket to a friend or neighbour than to do it through the ticket exchange (although of course I wouldn't dream of violating the terms and conditions of the ST in this way, personally.....)
I think that once you've used the system a couple of times, the £25 voucher is a real disincentive to using it again. We got three or four at the end of last season when the exchange was activated, when part of our family group couldn't attend the match. But to be honest, there's nothing left in...
