favors... need help

Does anyone know of a good website to buy glass jars from?? I'm looking for nice glass jars with tops for our favors. I was going to do personalized M&M's in our wedding colors and put them in a glass jar, put a label on it & tie a ribbon around the top. Is that a good idea?

Has anyone done anything similar? If so, where did you buy the jars from.

P.S. I'm not looking for jars with those silver or gold caps on them. I'm either looking for the ones with cork tops or glass tops.

TIA!

I think it's a great idea - just search for crafters' supppliers online and then put quotes around 'glass jar' - I'm sure something will come up! Let me know if you need more research - goodness knows I love that hehe.
