Yes, you can actually filter the suppliers search by order requirements (no minimum order to brackets of price order required) , by category and sub category, by location (drop down list of countries) and by type (dropshippers, wholesalers, manufacturers, liquidators). You can also choose to filter those who can ship internationally and/or does not requiring a Tax ID. :)
To use and search in the directory please click on the Directory link you will see above. You will be led to a page with a Search box where you can type the product/keyword that you need suppliers for. To see the options I mentioned above, just below the green box for Search, you can click on 'More Options'. Set the filters you need and click on Search. :)
Let me know if you need help doing this. Take care!
