Sometimes they take awhile to stock them up. I end up going to Olivers at the Prince's Building or that supermarket at Pacific Place when we get desperate... staple snack for bub.
Do you mean Weetbix (Australian) or Weetabix (UK)? In HK Weetbix (Aust) is called "Bixies" and is available at Olivers and some Wellcome supermarkets. Stocks can be a bit hit and miss, so stock up when you see them.
Parknshop in Happy Valley always seem to have a stock of Weetabix, not sure if that's close to you or not. I assume you can possibly order it online from them too....
Thanks everyone. I am happy with anything that looks and tastes like Weetbix. Sounds like I was just a bit unlucky not to find them at the two supermarkets I went to. I will keep trying and stock up when I see them.
