Ako odlučite da kupite opremu po niskoj cijeni, provjerite da li vi komunicirate sa stvarnim prodavcem. Saznajte što više informacija o vlasniku opreme. Jedan od načina prijevare je da se predstave kao prava kompanija. U slučaju sumnje, obavijestite nas o tome radi dodatne kontrole, putem obrasca za povratne informacije.
Prije nego što odlučite da izvršite kupovinu, pažljivo pregledajte nekoliko prodajnih ponuda kako biste razumjeli prosječnu vrijednosti odabranog modela opreme. Ako je cijena ponude koju vam se sviđa mnogo niža od sličnih ponuda, razmislite o tome. Značajna razlika u cijeni može ukazivati na skrivene nedostatke ili pokušaj prodavca da počini prijevaru.
Nemojte kupovati proizvode čija je cijena previše različita od prosječne cijene slične opreme.
Ne dajte saglasnost na sumnjive zaloge i plaćanje robe unaprijed. U slučaju sumnje, nemojte se bojati da pojasnite pojedinosti, zatražite dodatne fotografije i dokumente za opremu, provjerite autentičnost dokumenata i postavljajte pitanja.
Najčešći tip prijevare. Nepošteni prodavci mogu zatražiti određeni iznos kapare kako bi "rezervisali" vaše pravo na kupovinu opreme. Dakle, prevaranti mogu sa prikupe veliki iznos i nestanu, i više se ne pojave.
- Prijenos pretplate na karticu
- Nemojte plaćati unaprijed bez izdavanja dokumenata koji potvrđuju postupak prijenosa novca, ako vam je tokom komuniciranja prodavac postao sumljiv.
- Prijenos na račun "povjerenika"
- Takav zahtjev treba da bude alarmantan, najvjerojatnije komunicirate s prevarantom.
- Prijenos na račun kompanije sa sličnim imenom
- Budite oprezni, prevaranti se mogu prikriti iza poznatih kompanija, neznatno mijenjajući njihov naziv. Nemojte prenositi sredstva ako vam je naziv kompanije sumnjiv.
