If you can use last years edition, I'd do that. No need to waste money.

I never buy text books that dont specifically relate to my Profession. For example, we do Units which are related to Mental Health, Spirituality & Nursing Research. I didn't buy any of the texts relating to these subjects as I felt there were a waste of money for 1 semeseter.

However, if its texts relating to Midwifery which I will use for some time to come, I always buy the reccommended texts.

I agree with LimeSlice, get online. Fishpond is soooooo cheap and has free shipping. Ebay is good if your quick. I've never brought from Amazon.

There is always the library aswell.
