Yup this is expensive pet food but thought I'd post anyway for the snobbier pet owners amongst us ;)
Since the postage is £4.99 this is only a good deal for those looking to bulk buy. Postage over £29 is free so if you don't mind stocking up you are probably going to save a lot of money here.
Then again maybe someone has some vouchers for free or reduced postage?
In either case, plenty of BOGOF offers for Iams/Eukanuba right now, for cats & dogs of all ages. Online only.
Cat BOGOFs (300g, 1kg, 3kg, pouches)http://www.petsathome.com/shop/gifts/brands/iams-cat-dog-food/iams-cat-food/
Dog Iams BOGOFs (3kg bags)http://www.petsathome.com/shop/gifts/brands/iams-cat-dog-food/iams-dog-food/
Dog Eukanuba BOGOFs (3kg bags)http://www.petsathome.com/shop/gifts/brands/eukanuba-dog-food/
Even if you don't want to buy loads but usually buy Iams, you could buy 2 products with 2 free, still saving at least £5 with delivery included. e.g.
Iams Adult Complete Cat Food with Norwegian Salmon 1kg
x2 = £11.20
= £16.19 with delivery
Normal cost for four bags would be £22.40
