VAT back on exit Thailand. Chiang Mai > Bkk > Cambodia

[BuffaloRescue]

Hi

I bought a laptop in Chiang Mai. Im soon flying to Cambodia via Bangkok. Can I get the VAT back on my laptop I got the correct receipt from the shop I bought it from (yellow VAT receipt).

 

Im just wondering how it works... do I need to bring the original box my laptop came in, or just the laptop itself out of the country?

 

Does it matter that I am returning to Thailand where I am currently staying (on multi entry tourist visa) and will be bringing the Laptop back to Thailand? 

What do I do/say?

 

Also where do I claim the VAT? In Chiang Mai Airport or Don Muang? And ill be in transit through Don Muang.
