Issue with "Throw 5 chips in fountain" Task

[RavynMadPegasus]

I am basically being forced to spend my lucky fountain chip on a item that I don't want,
just to keep my daily task streak going.
Why is there not a option to throw your own chips and not use the lucky fountain chip I bought?
I think that's unfair.

So I've only ever had 1 lucky fountain chip! I've never seen an option to buy more.  Luckily I've been able to get some items I want by throwing regular chips,  but most times I can never get the item I really want! Having some lucky chips would be good.  How can I get more???
