Well my last lot from the USA cost £55.87 (inc shipping) for 7 sets (one being mandolin and another 12-string, which are a bit dearer - so call it 7 and a half sets) about £7.50 per set. Beat that! They are £10.40 per set if you buy ten sets at stringbusters (just been on the site) plus shipping which I don't know what stringbusters charge. Of course if the customs had caught me it would have been different...
