Ok, grab a seat... shipping for 2 fuse holders with screw caps and fuses would be roughly 15 Euros! Since they're not that heavy (250g each) I guess a heavier parcel wouldn't be much more expensive, so if you wanted anything else shipping would be less costly.
Regarding the French plugs you once wanted: I'm sorry to tell you just after I promised them to you the Czech supermarket stopped carrying rewireable plugs...
