Dear K Phornthip,
I apologise for causing some confusion. There was a shortage of the product and I managed to get only 1 amp last week. However, I have since managed to obtained another 2 amps from a different country. If all goes well, I should be able to deliver the remaining 2 amps at the end of this week or early next week.
I will inform you again before we deliver the 2 amps. Thank you for your patience.
