A tenners worth of PrePay for free - Get in quick!

LU/Oyster have just launched a new 'Auto top-up' feature on all prepay Oyster cards, where you can now set up a credit card to be charged automatically an amount of your choice whenever your pre-pay balance falls below five pounds.

Handy in itself, as it means you'll never have to queue up at a ticket machine ever again, but if you get in quick - NOW - they're also giving a £10 discount to the first 10,000 to sign up with this new feature of Oyster... I've just done mine! I suggest you do the same...
