I have ordered 3D DLP glasses from Amazon US through ishopinternational
So far it has been a good experience. The customer service was quick to respond on phone, no IVR or waiting in queue. They are very fast in giving quote on emails as well.
The shipping charges are also competitive, lesser than Amazon global shipping charges. They gave a discount of fixed Rs.200 on shipping charges for entering HOLIDAYCHEER as the offer code.
[ Somehow free shipping (for >$125) did not work for me on Amazon. There was no such option during checkout. ]
AFAIK IshopInt offers two type of import.
In first method, you can just give them the URL of the product, they will give the exact quote including customs along with an URL to make the payment. Once payment is done, they react very quickly. In my case, within 30 min they purchased the item and its supposedly on the way to their warehouse in US now.
They keep updating us at every stage through email. Quote for the chosen item... Payment successful. Order Placed. Product Purchased. Item received at warehouse. Item shipped to India. Item received in India. Item on the way to home. etc... That's good.
Oh wait. I have not recommended them yet. Lets see how effectively they fulfill the order.
Second method offered by this site, is actually managed at PPObox.com which is almost same as first method except (i) you have to place order yourself and ship it to the given address and (ii) that its a different company.
IshopInt have just advertised them on their website and they pretend its the same company. But its evident from the fact that you have to register all over again. I am not sure though. Just like alibaba.com they may be having different company names.
