Those two sites are not meant for inexperienced people. You can certainly find a scams there, but they're fairly easy to spot: unbelievable prices, payment only by western union, sellers with no/little reputation... Personally, I've mostly had mostly good experiences with those two sites - almost all of the items I ordered arrived and worked well. The two exceptions was when I bought a very low price product, but I got a refund for it, and another example was when I bought a large lot of items at almost a 5th of their price, and paid by Western Union... it was my fault for not knowing better.
