Cheap Martini Glasses

Anyone know a cheap place for jewelry in reality?
I need like 10 martini glass necklaces, for very cheap, for a bachelorette party. Does anyone know of a site or store that could get a necklace or at least separate for about $ 5 per piece or perhaps less expensive? I know you can get gems like claire cheapy for like 2 buck flea markets and stuff but I do not know the web. Help please!
Walmart or you can try some of the jewelry stores line
