Seller from China

The seller is probably referring to their eBay store.

Some sellers manufacture an item only after you order it, or rely on another party to provide fulfillment. So, they list it, but if their sweatshop gets shut down, or they can't get the material, or the second party doesn't have the item, etc., the item won't be available. Human error comes into play, too. Seller thinks they have 10, but only have 5. Only when the 6th order comes in do they realize their mistake.

Assuming you paid by PayPal, you have 45 days to file a dispute. I just received an item from China. It took about 25 days to arrive. International shipping takes time.

Since you haven't heard anything, your item is probably on its way to you. I wouldn't worry about it yet.

Thank you sir,
Now more than 44 days since my payment, the item still not arrive yet. If I open case, its just cheap item but if I left negative feedback I worry that seller would no longer offer shipping to my country. It's not good for another member from my country that need another stuff from that seller.
Do I must let a few dollar just vanish ?

I need your enlightenment ....

Email the seller and politely ask when to expect your item. If you receive no reply (or an unsatisfactory reply), then consider whether to leave negative feedback. This is the best way to take care of yourself and your countrymen.

Thank You Sir, (Cartman)
at last, the item arrive at 47th day after payment. I still left positive fb for him, but i keep in my mind that would not buy again from him.
Thank you for your kindly reply. Its make me more understand about how to buy at ebay.

Best Regards
