These cheese bags will make your cheese last drastically longer. Plastic wrap condensation makes mold happen much faster. I buy Costco blocks of sharp cheddar and finish them myself, though I'll admit a certain fondness of cheese.

But also, most cheese mold is a surface only phenomenon. Remove what you can see and continue eating (doesn't apply to soft cheeses)
