Bread outside the fridge spoils fast. Bread in the fridge lasts longer but is less fluffy. In this household we refrigerate our bread and then toast it lightly if we're going to eat it straight. Most of the sandwiches I make are toasted anyway.
My parents used to keep bread in the fridge and I hated it. It always sapped the moisture from the edges and made it stale. I don't know what kind of bread you buy, but mine stays fresh for a very long time on the counter.
Imo, freezing bread is the better option if you want to preserve it for long periods.
