But the additional cost on the ticket would have more than cancelled them out. I went because it cost £12 (+£1 booking fee), once it had gone to £15 (£16 with booking fee) I probably wouldn't have bothered. £25 for me and my son for A CC cup game against Newport isn't worth it.
There was no travel voucher though. I paid £12 plus a £1.50 booking fee because the club website refused to accept the card belonging to the account my season ticket comes from (same card worked over the phone!). Then I paid another £3.30 return on the train meaning total outlay was £16.80, exactly what you quote as unacceptable. I'm not particularly moaning - simply pointing out for many that the cost was exactly what you said was unacceptable. Unless you mean £16 BEFORE the added extras?
