Thanks for the insight guys. And good idea Mel! Why didnt I think of that!
Will have to hide the money (from myself) though.... or maybe get one of those tin money boxes that dont open without a can opener.
I hadnt taken into account the postage either. I was just planning to buy them in the local baby shop. I gues it would be cheaper to get them online, or in bulk. Going to ask the local shop if they have customer loyalty discount system.

Thanks again you wonderful women!
