I am not sure whether i am suppose to share this or not.
If i am making a mistake mods please correct me.
Coming to an online exchanger there is one http://onlychange.com/ . I have used it a couple of times before.
But i advise you to test it before with 1$ or so and then proceed
Can we really exchange for just $1? As far as I know, usually online exchangers keep some exchange limit like $10 or something, as in swapgold.com.
BTW, I have found one more online exchanger http://us-exchange.biz/ where the rate is 1 PM = 1.01 LR, which is really quite a high rate. So I'm not sure whether it is a legit or scam.
