Use code 8110
Okay, so the discount should be £10 of a £20 spend on Full priced, but it seems that it's knocking a tenner off some of the sale items over £20 too.
I've dropped a couple pf examples below too. Maybe not everyone's taste, but you might find something. The "Get Deal" link heads to the Sale area, but as above, works on Full priced too :)
