Agree with japhrimel. Unless you live over an hours drive from a 24 hour supermarket I really wouldn't bother.
Can't find a link for you but research shows that you are more likely go give up bfing if you have formula in the house.
"Mainly for once breast feeding is established so that I can pump and my husband can enjoy the closeness of feeding him."
I really wouldn't bother with this either. Your DH can get close to your baby in so many other ways, bathing LO, skin-to-skin, taking them for a walk, changing them, dressing them, looking after them while you have a bath etc.
You will probably find that you have to sterilise the pump and bottles, express more than once to get a bottle. Prepare the bottle yourself. In short you will be doing all the hardwork while he sits on his bum telling you how he is helping you out. Get him to read this instead 
If you really want to be prepared I'd find out the numbers for all your local Bfing Counsellors now and pack them in your hospital bag just in case, you could also put the numbers of the Bfing Helplines in your phone. And if you're really organised find out where your local Bfing groups are and start going to them before you have the baby. Some Children's Centres and branches of the NCT also run groups for Dads.
