Well, I've Googled myself silly over the past 3 nights and cannot find one single supplier
in Europe who has a 4-string set of
La Bella 760FS or 760FM flatwound strings in stock 
. Various websites have other sets in stock, or advertise the sets I want but
don't actually have them in stock.
I know where I can get some in mid-November, but I'd rather have them now
.
So, if anybody here can post a link to an online strore that can post to Germany (for less than 10 Euros), I'd be really grateful to you
.
I give up! Where in Europe can I buy a set of La Bella 760FS/760FM strings -TODAY??
