I use epacket regularly for Aliexpress purchases. I have never had a problem. They almost always arrive with 3 weeks...max a month. I have several that arrived last weekthat were mid October orders. My oldest order, from early October, seems to be experiencing the oddest travel experience I have ever seen.
Here is my tracking number... LO299310187CN. Using 17track, which is more detailed than China Post website, it now has 26 scans and still has not been put on a plane! It just keeps looping around in circles to the same sorting centers over and over again. It has been to Shanghai, Nanchang, Yichun all 3 times!!!! They don’t seem to know what to do with it. The seller just keeps saying this is normal, but ummm no, it definately is not normal. I have ordered hundreds of epackets this year alone. I have never seen this. The seller has an excellent feedback rating, so I do not doubt their credibility, but with 44 days still left on the protection, it frustrates me because this was needed prior to December, and that clearly is not happening. I think the seller addressed it wrong and China Post has no clue what to do with it.

There is absolutely nothing about the order that would cause it to be returned. It is just some miniature toy plastic luggage bags for dolls. No copyright infringements on the bags or anything like that. As a matter of fact, I have seen the exact same bags sold here in Canada at the local dollar store, so they likely also sourced them from the same manufacturer.
