Yep, I have to ditto what Ken said.

And to add to it, you have to consider the amount of work involved in drawing and printing the plans, having someone build one and document the build with pictures and text for the manual, graphic artists to do the manual's layout, printing the manual, designing the construction of, and the artwork for a new, smaller box, etc. etc. etc.

And for the record, I do reviews for RCU where I document the assembly with pictures and text and in my full-time job I work with people who do catalog layout and I can tell you first-hand that these tasks require more work than you can imagine!
