I'm going to Macau and Hongkong this December.

(1) i plan to take the cotaijet from the skypier to taipa ferry terminal, my question is on my way back should i take the same route? or am i allowed to take another route? considering that i wont be passing by immigration in the skypier upon arriving at hong kong.

(2) is it sale season in Macau at this time?

(3) will i be able to buy something that i can actually wear back in my super hot country.

thank you
