Remember the premium prices we paid when CDs first came out? and for quite a while after.
In HMV, Southend High Street about a month ago, I noticed 'classic album' Cds at a fiver or less and vinyl at £20-£25 per single album and thought how things have changed. (Although, at least it seems to be mostly 180 gram vinyl now, as opposed to some of the thin, warped stuff shops used to sell - like a rollercoaster ride for your cartridge, with pops and clicks chucked in for your speakers)
I must have returned 80% of the vinyl I bought in the old days - they saw me coming and gave me the same ones again I'm sure.
