Ans: company makes more money cos they don't have to pay the person in the booth now!

I bought some arena tickets through the UK TicketMaster site the other week and was vaguely discombobulated by the ticket delivery options.

For just over £2 I could have the tickets sent to me by post. Or, for just over £2.50 I could have the tickets emailed as a PDF and print them out myself to bring to the venue.

So if I pay for the paper and I pay for the printer ink, and the same employee on the same door at the same venue uses the same barcode reader to read the ticket I printed off as they would do on the ticket they printed and sent me through the post ... that costs me more?
