As internet is such a powerful tool, journals are turning towards online and open access systems for better exposure and indexing, meaning that they need funding for managements. Even the classic journals are now adopting this fee-open access system. So don't be cheap, support open access publication. Among the best journals, General and Comparative Endocrinology has a free publication option. See https://www.elsevier.com/journals/general-and-comparative-endocrinology/0016-6480/open-access-options
