Submersible floral lights

Hey ladies,

I was wondering if anyone knows of a store in LI that sells submersible floral lights. I am trying to decide whether I want floral centerpieces or do my centerpieces myself. So I am making a mock up but I need those lights. I know i can order them online but if I don't like it I don't want to waste the money. So any help would be great. Thanks

I'm not really sure if a store sells them. you could check AC Moore or Michaels.
I know they have them online. Maybe try ebay? It might be cheaper.
