Q. What should I do if I have to pay duty tax to receive the goods?
A. This is your own decision. Since we cannot guarantee that duty tax will not be charged world-wide, you can:
- pay duty tax and collect the parcel;
- reject the parcel which will be returned to us and ask for your money back.

Well I had to pay duty tax and when I told them about this their first reply was this:
"We do regret for what had happen.We can advise you to pay the tax and collect your goods as we'll try to cover this tax back with your future orders with our company."
When I told them I would like my money back when they got their parcel back, the reply was this:
"We are really sorry for what had happened to you, but we are not responsible for the seized parcels by your Customs. Now we can't give you a refund as we have regularly shipped your goods and did not receive any of your parcels back. We know that sometimes Customs destroy parcels without sending them back to the sender."
These quys operate under several websites names.
I would not recommend these companies. My impression is that it's a scam.
The websites mentioned above look like websites that send their packages through customs. You can use a US based online company (if you happen to live in the US) and avoid these issues.
