It's a matter of principle.
The boy sent me a Thai bank account (of a friend of him) to which I transferred the money from my Thai bank account (no charges).
My experiences with international mail (letters and parcels; postcards are fine) are rather negative. About 2012 I sent my SIM card and some money (to top up my SIM card) to a Farang friend in Thailand, the letter disappeared. Four weeks ago I sent a parcel to a friend in Portugal, it arrived a week ago.
