The only other reference I can find to 'Green Wednesday' is a single instance that mentions the Wednesday before Thanksgiving, in America.
Speakers - Monitor Audio Silver RX2

I will think about it, summer sales are a tradition.
It will be only cables - both interconnects and speaker cables, it will apply automatically to ebay listings for the day from BST 12:30am on the 30th to 8:00am (to cover other time zones) on the 31st. It will also apply at the forum to orders for Statement cables or lengths not listed at ebay.
I have to have a secret otherwise no fun so you wont know the discount % until the day.
