I didn't see any in TESCO's tonight :-) Plenty of albums, but no singles. To be honest they're not cost effective to make. Why would people pay for a single when for a little more you can get the Now 9999 with oodles of tracks – any self respecting music person should be able to tell you which tracks would be in the top 40, 20, 10 or top three.
So making compilations isn't rocket science. I'll get me coat now :-)
