Download coupon, go to sainsburys store, buy a pack of Huggies newborn size 1 WITH your nectar card and take the mum & baby bundle to the cash desk with your coupon.
The bundle says it has a changing mat in it, and looks like it has some nice stuff in it.
I havent used this offer though as i dont have a nectar card or a baby! So if anyone uses this let me know if its any good !
Apparently you have to have a nectar card to get this offer.
