Any good music shop, and online. Ask your local high school music dept where they purchase theirs. A good music shop will be able to discuss the best reed to suit your ability and whether you use natural or synthetic material.
Any local music store should have reeds, and if they do not, then ask the music instructor at your school, I'm sure he/she would be willing to give you a reed.

Added: In today's day and age, I don't know if I'd take a reed from anyone. I'd like to see it in an unopened container, sold at a music store. I take it you know what number reed you need. You can also order these through the computer. Go for it! Do some Jr Walker and the All Stars stuff. Or maybe Cut Across Charlie!
Clarinet reeds can be purchased at most music supply stores. These can also be purchased online on sites such as Amazon, DHgate, and e-Bay. These are also available from One Stop Clarinet.
