Review: Good buy! - Great that I can still get these fuses for my aging, country house electrical system. Horrible that they're getting so expensive, even from desertcart. They were a buck or two just a few years ago. Can hardly find them at the hardware store anymore. I'm sure they'll be five bucks a piece soon, so I guess I need to find a lower amp replacement for my space heater.
