Rice Hulls or a Substitute

I’m going to be brewing a pumpkin ale on Monday, but I forgot to order rice hulls from NB. The only lbhs in my area closes at 5 today and is closed Sunday and Monday. I’m currently at work so won’t be able to make it today. The only stuck sparge I’ve ever had was a pumpkin beer and I’d like to avoid that headache. Has anyone ever found rice hulls anywhere other than a brewstore? Are there other viable substitutions that won’t contribute flavor?

Maybe throw it in one of these? They are pretty fine, but not sure how much it will hold back pumpkin.

Add the pumpkin and spices to a secondary fermenter the same as a fruit addition.
