It is a redemption price for customers who have purchased baby/child products for more than $100.
Since I used the Hang Seng Cash Dollars when paying, I can get $20 extra Cash Dollars, making it even cheaper.
Actually we also use Chicco浴帽. It helps to stop most of the water from coming down the face but some still go down to the eyes, nose, ears ... Since the chair is multi-purpose and cheaper than similar product from Ikea ($99 and a bit smaller), I think it is okay to try it out.
