I just had a call from one of the NB factory shops... she told me that the factory had some 765's in for just £14.99!!
She told me that they are contacting peeps who have ordered them in the past and offering them at this price, but i'm sure you could just phone and ask anyway.
With postage they still come out at £19.49.
I've only just ordered 2 pairs of 766's a few weeks ago, but I had some of these anyway...i'm a sucker for a bargain
The factory shop that called me is on 01768 774631
