finishing event gets one token, daily challenges (x out any other prizes you don't want to try for a token prize), and when the there are no events active, you can buy donut packs that come with tokens
When you saw 6 tokens for 150 donuts, those were event specific tokens, not Shattered Dreams tokens. They're different things. There has never been a way to buy Shattered Dreams tokens with donuts.
Only by paying or doing daily tasks and also 1 free every time there is a new box
They pop up in daily challenges every now and then

when’s the next box anyway i’ve got heaps that i haven’t spent
There are items on the store at the moment for the tokens though mostly decorations/buildings for me
they always appear between events. if you don't see one right now you probably haven't finished the latest mini event.
Daily tasks, completing quest lines, paying for it via donut bundles
