I went to the expo yesterday night.. besides avent and cordlife, huggies is there too. But their promotions were nothing exciting at all. I think most pple went to buy baby clothes and accessories. Carters bibs were selling for 5 for $15, towels (with/without hood) ranged from $7-$16, Carters rompers from $2 or $3 onwards, nursing bras $12 for one, $30 for three. There was a stall that sold those huge playmats too. The cheapest one on offer was $99 (made in china), the rest from Korea were more expensive in the mid $100 range.
Hope this helps!
