Interesting. With all due respect, I think you should redesign your site www.nerdkits.com
The elements are really aligned in a logical fashion. It's pretty aggressive on the eyes when you see huge yellow boxes with the prices on the right.
The stuff that's supposed to grab my attention, doesn't. "Invest in yourself: learn by doing. Read on to learn how the NerdKits philosophy is implemented in our kits, and why other electronics kits will leave you intellectually unsatisfied." is DISTRACTED by the "Updated Thursday, December 17th, 2009:" div.
I would highly recommend outsourcing your design to some place (even some place that could do it on the cheap).
The product looks amazing though!
