Conversion Rates

[jconnel]

For those of you who track conversions I would be interested to know in general what kind of conversion rates you get and wither your products are tangible goods, services, or electronically delivered goods (like e-books or software).
Even more interesting would be if you have a different CR for PPC vs. Natural search traffic.

My site sells tangible goods.
PPC CR ~ 3.3%
Organic ~2.2
Overall ~2.8
