I'm trying to get rid of these items. I don't know what the trees are worth but I saw them in stores for 25 diamonds sometimes.. Anyway, you can buy or trade, just comment offers.
I also have spikes, promos, collectors and more in my shops. I'm most definitely willing to lower especially if they aren't selling, I'll sell for a lot cheaper.
My user is the same here as AJ, just copy and paste.
