You don’t need to hoard leaf tokens!
I keep on seeing post where people were hesitant to spend LTs. The game is giving us 50 each LT for leveling up and you get a ton of LT via participating in the events (each stage is like 50 LT). The Guillvers ship ( a bit less about 10 LT per island) also brings LT and also leveling up happy home room ( 50 LT every or so levels). Then you can trade your bells for LT every months too……
I personally just use complete ticket for special furniture over 100 LT. but you can literally spend on it and not worry about getting low.
I also spent the 200-300 (however many) LT for the crating upgrade ( from 24hr down to zero. Everything is instant) which is so worth it. I gotten the LT back just from leveling up and playing the events.
EDIT: Also keep in mind there is a deflation in all prices (10x) across the board for items. That means more spending power.
So don’t wait til the cookies or the traveling merchant goes away then you need a complete ticket which is rare and more valuable than LT. I always get 5 cookies box for free stamp to trade for whatever item.
Also every month you can trade your bells for LT as well.
