I have been hit with the scam outlined by Crossy twice, both times ordering Thinkpad laptops: one Lazada Thailand and just a few days ago, Lazada Philippines. First, I want to make clear that in both instances, Lazada was totally co-operative and refunded my money.
The first instance, instead of a laptop I received a small plastic envelope with a "Jade" Necklace inside. Interestingly and this is important to note, the contents window on the envelope label stated the make and model of the laptop I had ordered. I immediately contacted Lazada and initiated a return. I then got an SMS from the seller, like the letter saying the necklace was a gift in compensation for the delivery being late and to expect the laptop in a few days. I called Lazada CS, asking if I should cancel the cancellation and the CS agent suggested I wait a few days. Of course no laptop ever arrived. The Philippines was pretty similar. The laptop was to be a Christmas gift. A small package enclosing a cheap ring was received, the package label declaring a laptop was inside. Again, I quickly initiated a cancellation with photos included of everything. Lazada did insist that the ring be returned to them which entailed dropping it at the express office. A full refund was issued the next day. I have successfully purchased several Lenovo Thinkpads on Lazada but it has always been from domestic sellers based in Thailand. Both instances of the scam were overseas Chinese sellers.
