They have some giveaways

I believe I saw some "gluten free-ish" options but I don't know for sure

Don't think so, but hyvee has started to sell donuts wth Butterfinger, heath, snicker toppings. Very good.

Yes but always out when I stop in to get one.

Yes.

I don't believe so.

Who delivers for them?

We make them on Monday nights to be ready on Tuesday, and whenever else we put brand new oil in the fryer. So there is a chance throughout the week but best bet is earlier. And they are, indeed, in a smaller box on top of the case. And it is a special selection.
