I'm more interested in the parts than the packs. I'd buy a set with great elements, or a large selection of a single element before I'd buy a pack of loosely related parts that cannot form a construction. I think that's the general consumer feeling, but if you found them at a low enough price and large enough quantity in a retail shop, the urge to impulse shop would be quite great. I'd be tempted, but I'd still rather be a smart shopper and plan a bulk order.
There is no life I know to compare with pure imagination. Living there, you'll be free if you truly wish to be. -Willy Wonka, 1971-
