I don't have AP, many AP sifu here will advise you later
however just my own opinion, it is your first AP, please get from either Boutique or AD
from what i learned in this forum, usually AD provide a more reasonable discount as compared to Boutique and whereas Boutique usually have more variety of models
please enjoy the whole process like taking medical leave on weekdays as less crowded compared to weekends, put on your best clothes and have a nice breakfast and drive your way to Starhill
when in Boutique, ask for a cup of tea or coffee, if they have Nasi Lemak please order as well since you are buying, then please fully utilize whatever they can throw at you
once close deal, ask for freebies like calendar, catalog from 2001 to 2016, polishing clothes, travel pouch and whatever they have
ask them to wave your Strahill parking if possible
