I bought three Sony laptops from them for $380 each and paid them via Western Union. After that they wanted $500 more as import tax. I said I can offer them company who will do it legally, but they stopped to answer me.

Wiring money to a vendor does not equate to a scam. The jackass above me is spamming bad advice.

Furthermore, they obviously have no clue what duty is.

Hey SEO, you have no reason to call me a jackass. Eat shit you rude asshole
