Crystal Napkin Holder Does Anyone Know Where I Can Buy Silver (doesn't Have To Be Real Silver) Or Plastic Napkin Rings For Cheap?

Does anyone know where I can buy silver (doesn't have to be real silver) or plastic napkin rings for cheap? - crystal napkin holder

I spoke very low as 50 cents each or less .... I am interested in the decoration of glass at my wedding, and they would need about 250 of them. I find nowhere cheaper! Thank you for your help =)
