My you are very stubborn. Post that statement from Lazada. Has anyone on this forum ever paid 1 baht for VAT and import duties on Lazada purchases? Step up.
No, I'm not being stubborn, I'm responding because I'm correct. "Stubborn" suggests that there is evidence that I'm wrong, there isn't and I'm not.
You're the one that made the initial claim that all Lazada purchases are duty/VAT exempt, not me, so it's you that has the obligation to "step up" and justify your claim. My proving a negative by providing evidence for something that does not exist is not the way it works.
Nowhere on Lazada's site does it state that all oversea purchases are free of taxes. If that was the case it would be splashed all over their site as something no other site could offer and a huge benefit to buyers...but, oddly, it isn't.
Just because a Lazada item is not selected for examination coming into the country does not mean that it's duty exempt, Thai Customs are not able to check every item coming in by post.
