Not getting it either unless I have a windfall of gems. Got the living wood tree which is one of the best buys ever, I can stop collecting white petals finally.
I don't do the fruit trade as I can't undersyand why I would trade rare magic fruit for regular fruit, I remember one time I did it I got stuff like tomatoes!! I am not short of golden apples, I have four apples trees that I could collect from more often if I wanted to. I do trade in for gems but it is nuggets that are harder to get. Then I used to do the rare fruit trade but have stopped since it isn't worthwhile either
