Is it worth keeping spares of the big PAL fuses?

Do they ever go out? It's $4 for spare mini blade of each size but $20 for the big ones.

I've never blown a fuse beyond my own stupidity. The more accessories you add the more circuits are likely to blow but more often that not it's things like the map light circuit and dash, etc so just the mini-blades. You should have some extras pinned under the cover inside the engine fuse box anyway.
