Hi there, first post so go easy!
Blacks currently have 50% off their Men's North Face Zeus Triclimate jacket. If you use the voucher which was posted earlier:http://www.hotukdeals.com/item/288921/20-off-everything-at-millets-blacks/
this gives you a further 20% off so the price you pay comes down to just £76 for an excellent jacket!
The 50% offer is also available online where the jacket has £30 off as well. So online you pay 50% of £159.99 = £80. Just put in the code TNF50. You also get free delivery before 10th December!
I have not been instore to see if the jacket is discounted by £30 there as well. If so, you could get it for as low as £64 (unconfirmed).
They also have some ladies jackets at 50% off instore, but I can't see any online. These are the tri-climate jackets which have a removable fleece which you can also wear on its own.
