Hi Andrew.
Yes, tracking is important... so you know what promotional
activity is working for you.
Well...
I just happened to notice another post in the ads section
here that is offering a free tracking service.

The idea is that with each separate ad campaign you use
a different link - and this service (there are oodles of
other similar services that do the same) gives you unlimited
links. You can log into their site and check how many
clicks each promotional thing you do gets. However they
may not tell you what generated the sales, but any info
(eg, how many clicks an ad in xxx got you) is better than
no info.
Cheers,
Gary
