Does anyone know where the top-ups option is? I chew through APD these days and always liked to know I could top it up for cheap upgrades etc. However I never did. And now, I can't find it, as any Google link that discusses it goes to a page that has now been removed since the card is no longer available - yet it's supposed to retain benefits through to October so I'm assuming top-ups will remain available too? If so I'd like to do a big bulk purchase now.
