Here's how I do it: use the categories on the side to narrow down what I want, then use the filters at the top. (e.g. Drugs>Ecstasy>MDMA, then use the country filter, the no FE filter, and sort by price, navigate to the ~3rd page and you'll find a bunch of listings for 1 gram of domestic MDMA sorted by price). The only product it doesn't work too well for is benzos; they can be listed under 'Prescription' or 'Benzos', so you have to browse both categories. For most other common drugs it's great.
The only thing I use the search bar for is to search for vendor names.
