Hay help for hamsters!

[gemmashaw]

so today i was wondering about hay for hamsters.
i am aware it is not needed in the hamster diet but i thought it may be nice for a hamster treat!

i don't really want to spend alot on something unneeded...
so does it have to be timothy hay?

is this hay ok? even if its bedding....

or is this alfalfa hay the best option even though its expensive and big and a bit of a waste because of the size?

thanks
