I have been getting a couple of buyers lately trying to get free stuff or try to exchange their item with me saying Item is defective send me another. The whole thing is The merchandise i sell is authentic Brand new and factory sealed same as bought from a brick and morter store. target Best buy walmart. So i Know they are tryng to attack one of my mant=y accounts. Just very odd 3 in a week defective?? No way. I have actually never had a defective item that was storebought. I have to watch and start checking these buyers :

The first early warning of these kind of buyers is when they ask a lot of questions before they order.

Particularly when they ask about return/refund policy before hand, it's a strong indicator that they intend to make a return... or at least get a refund.
