Millwall fans have a £2.40 booking fee AND a £6.50 transaction fee on top of their tickets. £8.90 in fees for a £15 ticket if you're an OAP buying the cheapest ticket
It's a transaction fee per order, not per ticket. And the £6.50 includes secure delivery. http://mobile.millwallfc.co.uk/documents/wembley201698-3121013.pdf
Having queued all night at Oakwell for tickets for the Cardiff match in 2008, I now love booking fees passionately
