Plum crazy

Piece on TV the other day about the fact that, despite a bumper season for English apples, supermarket shelves are dominated by apples from overseas, particularly France.  But what concerns me more is English plums - where are they?  Particularly Vics, my favourite.  There have been very few available for several years past now, and those that you do get are small ones with little flavour.  Where do all the big juicy ones go?  You can get Marjorie Seedlings, which are OK but very much second best in my book.  Anybody know anything about this?
