Purchase tips
Safety tips
Seller Verification

If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.

Price Check

Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.

Do not buy products which price is too different from the average price for similar equipment.

Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.

Doubtful prepayment

The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.

Varieties of this fraud may include:
  • Transfer of prepayment to the card
  • Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
  • Transfer to the “Trustee” account
  • Such a request should be alarming, most likely you are communicating with a fraudster.
  • Transfer to a company account with a similar name
  • Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
  • Substitution of own details in the invoice of a real company
  • Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.
