my friend got them for me, here's what he said :
"I have taken a look at the Lansinoh breast milk storage bags in Causeway Bay and Central, and all the stores selling this brand are running out of stock for at least a month. Your requested items are priced at HK$ 99.
At Causeway, I went to Sogo, Times Square and Lee Garden II. Only the 'Mothercare' at Lee Garden II sell your requested items.
At Central, I went to 'Eugene' (next to H&M) and 'Bumps to babes' (5/F Pedder Building). Only the latter sells your requested items, and the salesperson recommended another brand: 'First Year' which basically is the same with different price - HK$ 109."
by the way, the ice cube tray is from sogo, the silicon rubbery one (easy to pop the cube out) and heatable. i only have one tray, when i fill it up, then i place them into the ziplock bag (doubled just in case). I just label the bags 1,2,3,4 and on the fridge i have a piece of paper that i write 1 = date, etc.
thanks nicolejoy! I talked to a leader at LLL and she said it's not actually that important foremilk/hindmilk (recent research?) so she rested my worries and i'm just pumping whenever i can, which is usually at night...
