When buying or selling, you should always meet in-person to see the product & exchange funds. Follow this one simple rule and you will avoid 99% of the scams. If this is not possible, check out the sellers website and domain name. If it's a legitimate site, it should pop up on a Google search. Avoid sellers with anonymous email like hotmail, msn, mail2mail, etc...
DCIADS is not involved in transactions and does NOT offer any sort of buyer protection program, escrow services, or secure payment system. Any emails or web sites that talk about such systems are scams, even if they have the DCIADS logo. DCIADS does not handle payments, guarantee transactions, provide escrow services, or offer "buyer protection" and/or "seller certification". If you send money to these sites you sending money to a fraudster.
NEVER GIVE OUT FINANCIAL INFORMATION (bank account number, credit card number, social security number, eBay/PayPal info, etc.) to others over the Internet, even if asked to do so in an email supposedly sent by DCIADS employees.
NEVER WIRE FUNDS VIA WESTERN UNION, MONEYGRAM or any other wire service to an individual. Anyone who asks you to do so is a scammer.
If a seller claims that there are brokerage fees, import duties, or other such fees required to get an item into your country, do NOT pay the fees. You will not get the product and you will lose any money paid.
Sometimes when you post classifed ads, you may receive e-mail messages indicating that the buyer is sending you a large sum of money from which you are to deduct the asking price for your item and then send the rest back. If you receive a message similar to this, please ignore it. The cheque will bounce and you will have lost all money you sent to the other party. FAKE CASHIER CHECKS & MONEY ORDERS ARE COMMON, and BANKS WILL CASH THEM AND THEN HOLD YOU RESPONSIBLE when the fake is discovered later on.
Do not reply to emails saying that your help is needed to help take money out of a country and that you will be paid a commission for your help. Eventually they will ask you for money to help them take the large amount of money out of the country and once you pay you will never hear from them again.
Use common sense. If something sounds too good to be true, it probably is.
