This entire area is full of vendors.
A couple of tips: Check the box, check the IMEI stickers and check to be sure the battery is original. They won't just TRY to rip you off; it is a sport to them

Large stores are all fixed price, smaller stores and vendors are very flexible.
Also; make sure to get 2 invoices

I have bought both from Mong Kok (My O2 xda2) and Fortress (Sony digital camera) and was happy with both purchases. When I bought a phone, I put my SIM card in to make sure it worked. That same phone worked well when I came back to the US and put my T-Mobile SIM in it.
Happy shopping!
