See I do actually have a place for secondary wallet items (well, a main one, I think there's also a secondary, secondary wallet stash), which, was fairly recently (before lost season ticket) culled.
However it currently contains the following:
- Junior Blades Membership card for said 2.5yo x2
- Season Ticket for said 2.5yo
- Various supermarket 'loyalty' cards
- Morrisons Miles cards x6
- Nectar Card
- Decathlon Card x2
- Boots advantage card
- 3 different Riley's membership cards
- Caxton FX card x3
- Connect by Hertz card
- Forklift training 'licence'
- National Insurance Card
- G Casino Card
- Genting Casino Card
- JTF Membership Card
- Viraaj Loyalty Card x4
- Ikea Family Card
- Various unused and expired debit cards
- B&Q Gift Card
- Costa Card
- Sheffield Libraries Card
- Expired Camra card x2
- Revolut Card
Which I have of course been through about 10 times, in case every check I've somehow missed my season ticket
