Absolutely. We are really spastic when it comes to bread, sometimes it lasts 2 or 3 days, sometimes it would set until it got the "green measles"...
But in the 'fridge, it'll last a long time.
Edit: what kind of bread we talking about here? If it's "Wonder"..."bread"

you can use that as a carpet underlayer and then dig it back out and eat it a month later!
