Thanks for this great solution to Andrea Lener and craxx!

The `AND p.products_id = ep.products_id` in `catalog/admin/categories.php` WILL BREAK products editing / reading in of existing products if you have already products in. Therfore you have to add your products_id's to ebay_products too.

mysql> INSERT INTO ebay_products (products_id) SELECT products.products_id FROM products WHERE products.products_id > 0;
