I have the latest version of Baby Bargains, and I can't believe that you didn't mention looking at GoodWill or Salvation Army for infant clothing! You mention consignment shops, but even they are expensive compared to these two gems.

I went shopping at our local GoodWill store which has a special sale on the last Saturday of the month - all clothes are 50% off. I was specifically looking for maternity clothes, but came across some adorable and brand-new-looking onesies and outfits for $.25 each! I bought five items of clothing for $1.25. You can't beat that for a bargain. Plus, you're helping people in your local area by patronizing these shops.
