I did not get a white christmas tree either. If it is still available, I would like it. I will pay you up to 500,000 bells in-game for that item alone.
I wouldn't say that they'll have trouble selling it, it may be slower, but I do think they are still in demand. So far it's only been released in Japan and NA, meaning that the rest of the regions don't have it yet. It's still a hot item, and these forums cater to players all over the world. I'd keep it listed if you really want to sell it, OP. I'm sure you'll find someone who wants it!
Umm I dunno why it didn't work for you guys, I logged in today and Pete gave me a letter from Nintendo. It said "thank you for using SpotPass" and had a white festive tree in it, and I also got 15 Meow Coupons.
Is it opt in? I have it on for awhile now. Strangely, one of my town in my physical copies has it, the other two(1sigital and 1 physical) don't have any tree do I need to physically be in the spotspass zone?
Yeah, he didn't show up for me, no letter, no coupons. Changed clock and checked other characters, still nothing. Oh well, I'll let you know if it comes late.. though I doubt it will.
Edit: Never mind, just got my tree. Odd though that it wasn't delivered until now- I got the blue spotpass notification on time. Weird. Well, at least it works now.
