magento: bulk delete products via import/export facility?
This is an older question but maybe this answer also helps somebody googling.
Bulk delete of selected products is really easy with MAGMI I use it in the magento project I work on (I'm not affiliated with MAGMI creator.) The docs describe a bulk delete via csv but if you use the sqldatasource plugin you can do the same by adding the magmi:delete column in your table.
