Reposting this deal since it's been a couple of months since I last posted it, there's a new special offer, and the discount code still works!
Boots has Cow and Gate baby cereals on special again, and here is a parenting club discount code that seems to work in conjunction with that offer.
the 125g and 200g boxes are 2 for £3 and if you're a parenting club member, the code PCTNUKW takes an additional £1 off each box.
So I just ordered some boxes at 2 for £1! - 50p a box!
The code only works if you're a parenting club member and logged in. You also get 10 points per £1 spent with the parenting club, and free click and collect at boots, plus there's the potential for cashback, although this may be declined in conjunction with the other offers.
The code only works once.
Some of the variants are out of stock.
I didn't check if it works on the 250g and 330g variants that are 2 for £4 this time around, but it did last time.
I don't think it works on the plain baby rice 180g (It didn't last time, but I haven't checked this time)
