I store my bread in the fridge and never heat it up. I just make a sandwich and eat it as is.
Because the article doesn't make it entirely clear: to "de-stale" bread, it's not enough to bring it back to room temperature. You actually have to heat it to the "gelation point" (140°F) to undo the chemical reaction that made it stale in the first place. [1]
So even if you don't want it toasted, a quick zap in the microwave will improve its quality immensely.

Generally $3-$5.
