iMac Retina 5K in Newark, Nottinghamshire for sale

I purchased this Mac back in April this year as a gift to myself before my education discount ran out (was planning on using it for work after I'd finished uni.) AS it stands I think I'm going to stick with my PC (software etc). It has been out of the box and used once but other than is as new (including wrapping etc). The spec is the slightly higher one: 3.5GHz Processor 1 TB Storage * 3.5GHz quad-core Intel Core i5 * Turbo Boost up to 3.9GHz * 8GB (two 4GB) memory * 1TB Fusion Drive1 * AMD Radeon R9 M290X with 2GB video memory These would normally sell for £1849 but I'd be looking at £1730. No offers please. Would rather not send this due to its value so happy to exchange in person. Many thanks,
