Instructions:Only open to new customers (but you don't have to open a Very account, just pay by card) and it's not difficult to fabricate a new account of you already have one.
It's worked for me and my mum already, so it seems like a good one.
Useable on their 3 for 2 offer as well.
My example: 1 pair of slippers - £10, another pair £10, Superdry scarf £14.95 = £34.95
Take away cheapest item on 3 for 2 = £24.95
Minus £15 off code = £9.95
There may be a free delivery code somewhere but i couldn't find one.
