hershey, I blew through $85 in two weeks, generating a whopping 7 hits/0 sales with adwords from google. Not saying it won't work for you, but you have to be -VERY- careful about your ad. Make sure the ad is focused on specific items and you might do well. I focused on a general topic, just to draw people into my site, and took a shellacking. From what I have read, people have better luck purchasing PPC
from places like www.findwhat.com
etc. In this way, you only get charged when an individual clicks onto your site, instead of being charged for 'impressions'.
I did read somewhere, though, that people who have adword campaigns with google tend to rank higher, though, so there might be other, less obvious advantages to having an ongoing adword campaign. Not sure about that, though.
