Due to rampant online fraud, great care must be taken when buying DVDs and series sets on eBay. There are many Internationally produced "knock-offs" out there that are deliberately misrepresented and sold as US produced versions, and their target market is the US. Sellers in another country cannot be prosecuted by the US for fraud. I have learned that in Shanghai for instance, you can buy any Star Trek series season on many streetcorners for about $1.00 US, each. Duping US buyers for more money is a huge attraction. Part of the problem is that expert hackers have hacked their way into eBay's system and managed to access and use old US based user IDs, ones that have not been used for several years. Example: I have seen several sellers use exactly the same listing under several different seller IDs. If you check the seller feedback, it is always a low number and there has been no activity for several years. The item listed is represented as a US produced set of DVDs, but what you will receive is a cheaply produced knock-off. If you attempt to contact these sellers after you receive the item, you will not get a response. One or more buyers will complain to eBay and eBay will then remove the listing and advise you to contact your bank or credit card company. Buyers need to be more careful and study the listings carefully and then they may not be so easily duped. Some buyers actually accept it when they receive an item that is dramatically different from what they thought they purchased. This is part of the problem, not enough people complaining to eBay. If you're not 100% sure you're bidding on a US produced set of DVDs from a US based seller, don't bid on it. I generally trust sellers who state in their listings that they do not sell bootlegs, pirated copies, or knock-offs. Trust your gut instinct and go with it. You'll save yourself a lot of hassle trying to get your money back if you are not satisfied with what you receive. International sellers are not the only culprits. There are dishonest ones right here in the US too. You might want to think twice before buying from a seller who keeps their feedback set to "private." If you can't see the feedback, you just might be shooting yourself in the foot if you go ahead and buy from this seller. Happy buying and good luck!
