Revere bowls

Do you know where I can find cheap plastic revere bowls?
I am considering doing my own centerpeices, but when I google revere bowls all I get are these really expesive silver ones.

I got them for $5 during their X-mas clearance, but the same metal ones are sold on their (target) website for $19.99. I was told by florists though that spending more than $10 is not worth it, you can get them through them, but they are usually plastic or rented. My guests can keep these. target bowl link
