You are spoilt for choice when it comes to bargains at H&M. They have been pretty generous in the latter part of this year with order codes too, meaning you have been able to save £££'s on items like Childrenwear. Just now use promo code 6004 and you can save 25% off ANY one item plus FREE delivery. This code works on Sale items too and deducts that £3.90 delivery charge as well.
The choice is HUGE because this code will pretty much work on anything.
Here are some cool items that come at even better prices with that promo code: Patterned Nightdress* was £6.99 now £2.25, Rain Jacket* was £14.99 now £5.25, Disney Frozen 2 Pack of Tops* was £9.99 now £3.75, Two Pack of Pyjamas* was £9.99 now £3.75 and Christmas Pile Top* was £6.99 now £5.24.
Sometimes, H&M won't let you buy your item/s if the total is below £6 once the promo code has been applied, but it seems to be letting you with this one.
