Mary:
Congrats!! GB can be very daunting, glad to hear you are "in like Flint"!
You should be able to use your site counter to see where people enter your store from, who the referrering URL and engine was - if they came from GB, you should see that in your reports.
Trying out Google Analytics, pretty comprehensive reports, but I still prefer
AddFreeStats Used to use statcounter, but they haven't figured out yet how to keep your own visits from logging on a regular basis. You have to keep adding the cookie to block your visits, who wants to do that everytime you are working on your site??
As for shipping, I gave up on the bulk load, am now just spending half an hour or so every day, adding things by hand to GB. This way I know the shipping is RIGHT.
Why not add the shipping and a buy now button in addition to the link to your store? Get 'em coming and going

Just started doing this:
