We (CNYSubies) didn't need 5,000 either, but at the "5,000 free" price, it was hard to turn down.
I don't know if they have a lower price, lower quantity deals, but that's something worth considering.
Another thing, naturally, is that if 200 of us take an even share of the cards, that's only 25 each. Odds are good that you won't see 25 different SVXi soon, unless you cheat and drive past Earl's house, or go to Reading at the right time, but considering the number that get lost, stuck on our own walls, damaged, handed off to a friend for his friend, put in other Subarus in the event that, say, when you're out in the wife's Forester (ah, my Subaru gal) and you spot an SVX you can tag it up, double-tagged (unless you're gonna write down license plates!) and so on, 25 per can run thin quick.
Sure, 5,000 would cover over a third of the Stateside SVXi, and roughly 20% of the world's production run, but it's really not that much of a stretch when considered like that, yeh?
