Seen and bought in Ikea Edinburgh this evening. Not sure about availability elsewhere. Usually these offers are everywhere apart from the Edinburgh store!
EDEFORS glass door cabinet on offer for £129 with an Ikea family card (which are themselves free if you don't have one already). Normally priced at £273.06 apparently.
They had one set up on display with GRUNDTAL spotlights inside and looked quite attractive. Glass doors mounted in a sliding wooden frame hung from the top at the front so you can't see the track. The image on their website doesn't quite do it justice. The cabinet is made of solid oak, comes in 3 packages and weighs a lot.
