I will travel to Hong Kong with a group tomorrow. I want to buy an Apple 5 mobile phone. Do any friends give me some advice? thank you

I just got back. Franchisees have goods, but they need to book online. It's quite similar to our lottery ticket. I won't buy it either locally or abroad. I bought it from a scalper outside the flagship store in Central, which is more expensive than the store. The 200-yuan business hall is all contract machines with low risk.
