Massive thanks to VinylEddie in York for getting hold of this for me. Last Saturday (RSD16) was the first time I'd been in this shop. The Magazine release for record store day had sold out. They took my number and said they'd try and find it for me. On Thursday I got a call saying they'd got one for me. They only charged what it would have cost on the actual day (already going for more on ebay).
That's what I call great customer service.
