OK, so I went to Target to get the bounty bag. Here are the steps you need to follow:

1. Look at link I posted above to see where to get your New Mother (green) bounty bag. Don't pay the postage - go to the nearest pharmacy to you that has them for free. If there isn't one near you I wouldn't worry too much - it's OK but not worth the money.
2. Get the green bounty bag and find the Educational scholarships leaflet. On the reverse of that is a highchair competition and the voucher that you need to take to Target to get your Target bounty bag.
3. Go to Target customer service desk and give them completed form. Get Target Bounty Bag. Again is OK, but I would only really bother if you can get to the pharmacy and a Target easily. You get free 2 nappy pack, wipes, sudocream, Mother and Baby magazine, tonnes of leaflets and each bag has a $10 Target voucher if you spend over $50.

So am still not sure what the Target Baby book with vouchers is but hope all this is helpful!
