This category is for websites which sell science and nature related products online. Not all science and nature shopping sites are listed here, however, so please see: Shopping/Recreation/Science_and_Nature/faq.html Before submitting a site to this category.
Submit sites here if the primary product is a certificate attesting to something. Star naming services should go to the Star Names subcategory. Deeds to extraterrestrial property and other similar services go here. Tangible memorabilia (astronomy or space themed patches, coffee mugs, whatever) should be submitted to Shopping:Recreation:Science and Nature:Astronomy:Space Memorabilia.
