I myself also received a number of these E-mail before but most of them are FAKE because when I check there website I found out that they use yahoo and hotmail E-mail address and you know that if they are a big company they always have their own company e-mail address for Amazon website have their Email company address such as email@example.com not yahoo or hotmail address.
Here is some Tips which you can use to spot out scammer
1) Seller is not in the same country as the item (Hong Kong is not China for example)
2) Seller has minimum feedback of 10 and normally less than 20 (check the feedback, was it gathered in the space of a few days, is it from one cent sellers or round robin type feedback ?, if it’s private is it greater than 10 ?)
3) Seller uses stock pictures and descriptions (look closely at other items, you’ll see the same pics/descriptions used by different IDs
4) Seller doesn’t list / accept PayPal as an option (despite what they may say if you actually manage to contact them, China can accept PayPal)
5) Seller ID looks like a randomly generated mix of letters and numbers (recently registered and has minimum feedback. )
6) Does the starting price seem to good to be true ?
7) Is it likely you can contact the seller before the auction ends (one day listings on big ticket items won’t allow you much time to make contact)
8) Sellers ID is not new but hasn’t traded for some time before (offering big ticket items unlike their previous trading history ,or now trading outwith their previous geographic location, could be a hijacked account)
9) Seller has listed items outwith the reasonably correct category (even if you did have a big ticket electrical item you wouldn't list it in Stamps for example, these are frequently hijacked accounts and normally ask for email via a free web based email address in the listing to discuss Buy It Now terms)
10) Seller asks for contact by mail before bidding to discuss shipping or a Buy it Now price. (this takes you outwith any PayPal/eBay protection scheme especially if the mail is not through eBays Ask Seller a Question, generally the scammer will request payment by Western Union, this is not a secure payment method)
