Hey Spanners,
Nothing to add to all the above suggestions and apologies if you Know this already but maybe others reading don't.
Haggle like a madman, especially in shops where they don't appear to haggle!
Beware the good price on what you wanted but getting slid into "hey have you seen this Lens its a doozie" They usually have a shiny item of the week to push which is often not upto Par or over the top, price wise.
Read the small print on the warranty, anything going wrong with a high price item with a HKG warranty becomes a total pain and drama negating the value of the money you saved.
GOOD LUCK
