Earn Money With Bidz.com

It is a jewelry auction site and they are selling different type of jewelries like Gold rings, earring, necklaces, diamond..... at a amazing low price. Buy some of them and make great money online by reselling the jewelries at high margin.
However, something tell me that this seem too good to be true. So I did a search on Google and found a lot reviews from buyers. There are good reviews and bad reviews. Finding a good deals from bidz.com is possible but there are risks (getting the items not as described....) involve when buying in Bidz.com. Now I plan to do a test by buying an item from there and try to resell it on ebay or throung website to see whether I can make money. This could be a great online business opportunity. Check out the site, it is interesting.
