If you pre-ordered your deluxe copy of the latest Radiohead album, The King Of Limbs, one way to ensure an increase in value would have been to not open the package when it was delivered. You should sit on it for a few years (not literally) then consider selling it. That way you'll not only be offering a Mint LP for sale but also the pleasure of opening the package to the collector who buys it. Unless they decide not to open it as well. This strategy could apply to other albums with the potential to be regarded as future classics Make sure you have a Radiohead newspaper to sell with it as well. Mint vinyl double-LP copies of OK Computer (1997, £35) will also accumulate.
