I had been warned, but the prices were so damn good that i had to try ebuy7.com (taobao in some kind of english) anyway.
The order process and paypal check out work as they should. No problems here. First concerns came, when i was prompted to accept a so called "overweight freight agreement" which basically stated, that ebuy7.com can't guarantee accurate weight charges and that these will be reconfirmed, when the parcel is ready to be shipped.
I found this a bit strange, but was rather sure that the times ordered would not exceed 30 kilos, which was the weight based on which the freight charges had been calculated.
However, i was asked to send an additional 100 bucks or so, because the parcel became 37 kilos. Alternatively i could switch to EMS (instead of DHL), which wasn't an acceptable option. So we initially asked to cancel our order, which was answered with a copy of the overweight freight agreement. After a lot of hence and forth, i was offered a special price with FedEx, which i accepted.
When tracking my parcel, i saw that the actual weight was not even 12 kilos. Of course courier services go with some kind of volume/weight, which wasn't mentioned anywhere until i asked.
However, recalculating the volume/weight with the details from fedex still didn't sum up to 37 kilos. Not even to 30 kilos.
So we measured the parcel again when it arrived and sent the photos as proof to ebuy7.com, who had repeatedly claimed to do honest business. We requested to refund of the unjustified additional charges.
You can guess: we never heard from them again!
