well, it is a little strange, but after i visit the website, it is a real jewelry sales website, but i am not sure whether the jewelry on www.top10-jewelry.com are all real jewelry.infact, it is normal, a lot of seller offer free things in order to let more and more people know their website.i know another website, although not a website store, it is a cancer service website, which is also non-profit website. http://www.cancer-focus.com they just want to help some people, nothing else,that s good works.
if it is too good to be true it probably is. they are probably after your credit card number
