Scam through offering to buy a product at a price lower than its real value.

They simply call you as a representative of a certain product and ask you to buy it at a low price. Once you agree, they guide you step by step through the order registration process, including your personal data and address, up to the final step which is depositing the amount. But as soon as you press the transfer button, the full amount will be deducted from your balance, in addition to the requested amount.
