It is a bit odd. I think we were originally told to get the voucher in before the start of August, yet the part of the voucher you have has no reference number on and could be anyone's. They also don't ask for you name, or your season ticket number, so they have absolutely no record of who has claimed their shirt.
If anyone forgot to send in their voucher, there shouldn't be any problem collecting the shirt if you have the original voucher - simply tear off the piece you need to keep and get on down to the shop.
Still haven't found Pembo, Roger Nilsen, or Dane Whitehouse. I have found Brian Launders (twice), Iffy Onuora, Dimitri Markos (twice), and 'Chris' Benoit Croissant.
Boooooooooooooooooooooo! ;-)
