Couponing - who does it?

My Sister-in-Law and I got in a discussion about couponing today at our family get together.

We both agreed that there are a lot of advantages,

but we're unsure if we can pull off all the work to actually DO it.

So here's my question...

Do you use coupons on a regular basis?

If so, what resources do you use (ie blogs, do it yourself, etc)?

If not, why?
