Now, I have a collection of abt. 3,500 telephone cards.
I collect cards from:
the UK (BT),
and of course all types of radio-related cards.
This card is not a telephone card: every time I fill up my tank, it is
updated. If I visit these guys often enough, I can get a free entrance
ticket to EuroDisney (a few years from now) or get some free goodies.
