I forgot to mention it: I from Italy.
For EU Country there are new rules about duties. DHL has their custom fee, but even post have their rules.
With the post, in Italy, under 150 € we have to pay just the VAT, indeed I anticipated the fee I had to pay, but that not how much I was expecting.
Post delivery had delivered to me the package, and there's no DHL label, and the tracking have the TH, Thailand Post.
I have to say the deliver time estimated for Italy is 7-60 days. I often used the old Registered Mail deliver, except once, I always received my order in a month or so. This time less than two weeks.
PS As I asked early, does somebody know if I have to pay fee even for a small bag with four LED and eight nut?
