Sony 1Gb pro duo memory card for 3.99 plus 1.75 delivery. Add voucher code to bring it down to £5.16 delivered. Delivery is the same if you add more cards.
I realise that there are far cheaper deals out there for larger capacity cards but if someone is looking for a 1Gb card for a camera this seems like a good deal.
Delivery is free if you spend over £10! (Even if your discount code brings the cost below a tenner)
