Forum:Champion packs (how available are they?)

Thank you, im a first timer here, so please bear with me. Ive been recently checking out the champion packs, and i realized i want a couple of them, if i can. i was wondering if any of you guys knew whether they have reprint sets (unlimited) or if the production on the old sets stops?(when a new one comes along). Anyways, i live in san diego, california (USA), and i was wondering if anyone could tell me where i could get some. my local shops dont sell any. anyways, thank you.
