Buyer beware of TradeTang.com, DHGate.com, or any other "wholesale merchandise" website based in China. I ordered a variety of DVD media from these web sites, including fitness DVD's (P90x, Chalean, Zumba), as well as some television show DVD box sets. Everything that I received was a counterfeit, fake copy.
To anyone who deals with buying-and selling things online (eBay, Amazon.com, etc), it can appear really tempting to purchase DVD's, clothes, electronics, or any other item from one of these web sites like TradeTang, and make some fast, easy money reselling the items online. However, I caution you that this is a federal crime, it is a copyright violation, and the risk is not worth the initial reward.
There are a lot of people selling copies of DVD's, and other items online right now. You might think that you can blend in with the crowd, get in and get out, and make a quick buck. If something seems too-good-to-be-true, it is, and this case is no different.
I tried to get a refund from TradeTang, and they denied my request. I created a PayPal dispute, and they could not enforce a refund. Basically, I'm out the money I spent on these counterfeit items, and I threw them in the garbage because i don't want to be in possession of illegal copied DVD's.
Bottom Line: DO NOT order anything from TradeTang.com, or any similar wholesale website from China. Most of the DVD's don't work, and it is illegal to sell copied media, or fake products of any kind. Do not risk a lawsuit, fine, or even jail time.
