The bank tranfer was always an option but aparently not so much people is aware in this forum or not so much people have a bank account and a legal income, in any case i have been doing that for quite a long time and the cost is very reasonable around 6% if you send 1500 usd.
The only new here is that now a new player (correo argentino) will enter in that market to compite and put down the 48% comision of western union to 7%.
If it is a trap i don't think so as i have had 0 problem and i do this every month. Hope is a wind of hope and they rise the limit to 5000 or more lol, i know is to much asking
