All of a sudden the Clementine's in my local grocery store are the size of oranges.  Unfortunately, they have a ton of seeds and don't taste as good.  I don't eat oranges because of the seeds so Clementines have always been one of the only citrus fruits I eat.  Can you tell me why the fruits have changed?  I have never seen Clementine's this big in all my years!

Thanks, 
Christine
