I've just used Crown Currency for the very first time. I usually check the exchange rate on sites such as XE etc. Last week their live rates were E1.10, but this figure was for the Interbank rates, so you never get that much. On checking Crown Currency, they were offering E1.103, so I ordered my euros for delivery next week. Delivery in May, I think they're still offering E1.12.
Today the Post Office's rate is only E1.06
Will definitely use them again. Thanks to everyone who recommended them.
