A couple of thoughts...
One, a "catalog" product is pretty accessible, and many folks may already own it, or it may be a step down for their kite bag (said in the nicest possible way).
Two, there is something to be said for *sharing the link around* via Facebook, etc, so new folks see it... Other than the auto-post on KiteLife's page, I'm not sure fliers are sharing it directly with their buddies.
No stress, no fault, just dynamics at work.
