We have registered with the Thai Revenue Department VAT Refund for Tourists Program (VRT)
This means that most visitors to Thailand who buy goods from us with minimum value of 2,000 Thai Baht (about US$ 67) on any one day, can get a refund of the VAT (currently charged at 7%) if they depart through any of the international airports within 60 days of purchase and present the goods for inspection by the VRT staff.
Details of the scheme can be seen on http://www.rd.go.th/vrt
