Not sure which country you're in. If you're in the States, visit this site and type "petri dish" into their "SEARCH for" bar:

Answer 2

looks like you'll be spending about $30-35 between dishes and agar if you get the powdered stuff and mix it yourself.

I use amazon to price allot of stuff like this because there is so much competition on there usually you can get a good deal
