It still works and today is the 8th. Yippee (highfive) :)
Try making the order via their UK call centre - they are open 24/7 :O
Thanks so much for your effort posting this OP @joseph00334 ! Just worked for me on a phone order - Used it on the hozelock deal (plus a few other bits) which already were a great price! Mods, please un-expire.
Worked for me too via the phone - great customer service!
