You can contact 精英 Tel : 2344 6193. They have a shop 長期特價場in North Point 港運城 but I don't know they still offer special price HK$10 or not?
Yes. They offer me the same price in $120 per set. I will collect them at their showroom. They told me they can not offer me all books in exhibition price at showroom. If some of the books are nearly out of stock, they will give less discount to the walk in client and prefer reserving them to the school. ?-(
