The instant availability thing is such a huge part of sales. I know there are guys who plan every single thing they do, but I am certainly not one of them. Neither are most of my track buddies. Impulse projects, and buying, account for a large percentage of my purchases in racing. I don't think I'm alone in this, even outside my own biosphere.

I can think of at least 4 times in recent memory that I'd have jumped on some build tangent had blocks been available. The process was like, oh man, look at that. That would be a cool combo, what do the parts cost? OK, cool, doing mechanical math, getting the fire going. Then,,,,oh yeah,,,no blocks,,,what can I re cobble out of my existing junk.
