I learnt something new on my recent trip to RDCC so I thought I would share with you. I usually take my Jamaican dollars with me, I got a rate of 132 from M&S which I thought was good. I used the cash machine at L&M meat to withdraw some Jamaican dollars and was pleasantly surprised to get a rate of 146! Ok you have to pay £1 or thereabouts to withdraw but the rate is much better. Make sure you tell your bank your are travelling prior to departure and you should have no problems.
I know where I will be getting my currency from next time!
