I was eager for Pack 1 -- I've done similar things in the past with index cards for equipment, and these look much, much nicer and require no effort. And the cards didn't disappoint.
Like several others in this thread, though, I will not buy randomized boosters for a product like this. When people like Paizo "bust" packs to sell cards in groups I'll no doubt look into purchasing more. Given the increase in cost per card compared to the original release, though, I might have to pass even then.
