Candle Bowls

My sisters Sweet Sixteen is coming, and we want to buy floating candle bowls for centerpiece. We need about 40 of them, but they are really expensive. Any ides of where I could buy cheap? By the way, I have already checked the dollar stores, they have what I'm looking.

Do you have a Big Lots in your area?
Maybe an idea would be to find an alternative.
Such as Margarita, Champagne or wine glasses.

Or something clear or see through the cereal bowls cobalt blue or red.
You can put some foil under them to embellish.

TARGET!

What dollar store? They must have at Family Dollar or Wal-Mart.

IKEA??

Christmas tree stores or one odd / large / Ocean State Job shops much.
