Top-up a T-Mobile UK Pay as you go SIM Card abroad

[Bossman]

I meant a discount off the face value of the card. For example, I have never paid more than 17.50 pounds for a 20 pound topup voucher. This is the card that I use for my GPRS access while travelling (primarily because they charge the same 5 pounds/meg roaming or not), so I have had to buy quite a number of vouchers on ebay.
