When I eventually get mine (surname W) I think the wallet will be useful. Currently I use my Gold membership wallet we got on Season 2 of the Amex for my two together rail card and train tickets when we gone on away game train trips
All bank cards get renewed every three years or so, maybe they got a good offer to do it now rather than later. Also they might have found more and more cards were failing so want to avoid problems next season when we have 30k crowds most games.
