Forget selling your unused holiday currency back to the banks , post office or wherever you purchased. this is the only company you need. found there website on a thursday, completed the easy online registration same day. received the post office pre addressed security envelope on the friday from them. ..... sent the cash same day, received an e-mail form them saturday confirming cash had arrived. received an e-mail from them monday saying the cash had been counted,,,cheque arrived tuesday including the £7;40 post office insurance and posting fee. A quite amazing company to deal with, every step of the way they courteously e-mailed me re the status of the transaction. initially quite nervous about sending a large amount of unused euro to a company i had no knowledge of . 5 star service and absolutely the best buy back rates around. happy to recommend them to anyone.
