I've seen a bunch of responses (yes many from the same person but still) to your questions. I would say that's pretty good. It is over a weekend and a holiday one at that and many people on this list are only active during the week from their day jobs. I have had many questions go unanswered myself, but have also had many many answered quite well and I answer many other people's questions as well. But like others I do not get paid to sit and read questions on this list - so my activity on it waxes and wanes to the tides of what else is going on in my life. I am just glancing at the list activity for a minute for the first time in days and even now only have a few minutes to look. That doesn't mean I am not passionate about drupal.
As for your question you probably have to use arguments. Your main url will then be something like /categories/ and then your argument will define the next part (such as /categories/hard%20drives or /categories/20 with the products and then the product page - or however you define it. Search for some tutorials on using arguments and you should be able to get this working.

Normally people on a mailing list have some degree of passion for their project. It appears that this is absent from the Drupal community. I participate in other OS mailing lists where people help each other and I help people when they have a problem I can assist with. But for a project that claims to have so many adherents like this I would have thought somebody could provide some assistance. Apparently not.
