I use Iremit all of the time apart from the last where I used Western Union because there was no charge.
Why people use these tin pot outfits to save a pound or two is beyond me. Reminds me of all the people whose boxes never got delivered last year. LBC do it for a reasonable price and deliver as promised. What's the point in handing your box over to some tin pot outfit nobodys heard of before because they place an ad saying they can do it £5 cheaper.
