I second eBay for clothes - I'm expecting my first and have just bought a bundle of 16 sleep suits in newborn up to 1 m as I don't know how big my baby will be, and this cost me £1.99 plus postage (I bought many items so was combined)
They have arrived and most are unused, but washed. I also got 10 0-3 m babygros for 2.99 from same seller, these were used but you couldn't tell. It means that I've got a good selection of different sized clothes ready to go but for hardly any cost.
I'm more for the environment factor than the money although there's never enough of that to spare!
We've also opted for terry nappies, which we bought from mother are but I just found last week they do then in larger boots stores and you get more for your money there (plus 10points per £) so a little miffed but never mind! Still looking for a good quality nappy pail.
Sorry to change subject there op.
My DH and I did a but if research online looking at different lists, then compiled a list of everything we would need for the first 3m and went on a shopping spree (ouch!)
Although we got an awful lot for our money as before going out we compared prices online and got several items from amazon saving over half on quite a few!
We are BFg if possible but still got bottles and steriliser set as I will express so DH can do night feeds too, if he wants to. Of course assuming I can BF at all (my mum didn't produce any milk at all)
Hope this helps and always happy to answer any more questions
