Any way to combine different Humble physical orders?

[Solo4114]

Over time, I've purchased several HumbleBundles for Paizo products that included a physical copy of this or that item.

Currently, I have three physical products (The PF1e Inner Sea World Guide, the PF2e Beginners Box, and the Starfinder Armory) that are available to claim. All I need to do is pay for shipping...which brings me to my question.

I'm trying to figure out if there's a way for me to combine shipping for each of these three items into a single shipment, which I assume will be a good bit cheaper than trying to ship them all separately.

Is there some way for me to do this?

Bumping this because nobody's replied and I'd really like an answer.
