i have to order some replacement fuses, but it wouldn't be clever to order fuses for 1 euro and pay 7 euros of postage - only to do the same thing the next time a fuse blows. therefore i want to order a whole fuse supply to be well-equipped for a long time to come. therefore my question:
what are the most common types of fuses (amps / slow-blow / fast-blow) you would order?
