Instructions:If you go to ivillage.co.uk and select their offers section, there is a promotional code for 15% off a £35 spend.
It tells you to type 'ivillage' into the promotional code box at checkout
BHS online also have 30% and on some items 50% off school uniforms which is what I used it on and it worked fine. Got a good load of stuff and it'll beat spending the school holidays shopping.
There are also discounts on furniture etc which the voucher can be used with.
Hope this is of use to someone. :)
