I'm looking to buy a few Avent bottle caps. we've been using our 5-6 Avent bottles for a few years. and have only 2 bottle caps left.

I tried searching online but could only find US sites selling a pack of 4 for 4.99, but then i have to pay another US$9 to get it shipped here. couldn't really bring myself to doing it for a few plastic caps.

Has anyone seen stores selling them in HK? I tried calling mothercare and babies r us with no luck...
