I used to like Fantasy Jewelry Box, until I realized they were getting a lot of their products from Chinese wholesalers.
I discovered that after I found "Wendelyn's CZ Leaf Design Genuine Tahitian Pearl Solitaire Necklace", which FBJ sells for $38.95, for sale on eBay for $12.95 with free shipping (it has since risen to $14.71 + $6.14 shipping). If I did some more diligent searching, I could probably find it for less. I wouldn't want to, because this is actually a very unattractive necklace in person, but still.
I've since spotted a handful of other dupes. You could get "Willetta's Antique Gold Nature Theme & Ribbon Tie Necklace" for $21.95 at FJB, or you could get it off eBay for $4.99. If you want 240 of them, you could buy them off Alibaba.com for $2 apiece. FJB gets the shipping advantage here, since the eBay seller is located in China. It's a difference of about a week, based on my prior experiences with both FJB and Chinese resellers.
Don't want to drop $69.95 (marked down from $109.95!) on "Marie's Fancy Multi Color Crystal Peacock Bracelet" or "Maylen's Fancy Purple & Blue Crystal Peacock Bracelet"? You could get this blue one, red one, or this green one off eBay for as low as 1 cent starting bid. Heck, you can get the multicolored one or the purple one for $15.95 plus $6.95 shipping. Don't want to buy from that seller? You could buy the multicolored bracelet from this seller too. Or from this seller, who actually lives in the US. None of those costs more than $20, including shipping.
If you see something you like on Fantasy Jewelry Box, it would behoove you to take a look around at other options before settling on FBJ.
