Piggyback Fuse Holders - from high street?

[tigerstyle]

So not from the actual high street, but are piggyback fuse holders available in bricks and mortar stores? Maplin/Halfords? Have looked but can't find.
Would like some for a heated seat install.

i reckon they have them in halfords. Best bet is ebay or amazon though! Will be cheaper and you dont have to waste your time finding them!

Never seen this style before?

well thats all the black normal ones are. just with that one its a bit cruder. Might take up space though if you havent got an nch or so infront of the fuse box.
