Icelandic Krona

Hello - I recently came back from Iceland and still have some money left. 31000kr to be exact. Which at current rates is £206.57 in GBP. Obviously you'd get quite a bit less when buying it from anywhere else. Is anyone going to Iceland soon and would want to buy it from me? My thinking is that you get more krona for your pound, and I get more pound for my krona. Id rather do this than give it to somewhere like the post office and get an awful rate.

Thanks.
