I need a new phone and might have to pick one up when in Thailand so I would like to see what they have and potentially either a face to face sale or hopefully a website purchase.

This will be pre paid.

I would like another Zenfone 2 4GB / 64GB "ww" model but will happily look at other makes.

Try siamphone

Try Lazada.

For "face to face", go to Fortune Tower just above the RAMA-9 MRT (subway). Large variety of dealers and selection. Prices generally posted. Lots of Asus phones on display but you will find little variation in price, dealer to dealer.

Nasaphone has a comprehensive priclelist and it's updated daily (look for the dropbox link). Prices are generally low, sometimes among the lowest I can find. They have a shop in MBK and seem to do both wholesale and retail. If nothing else it's a great point of reference while shopping.

You can drill down on a model to get all the reported recent prices people paid at various outlets and shops.
