Offerings for Ipos, Orobas and Gaap?

Hi I am starting to work on these three to have more clarity into some conflicts and deception going on in my life and how I want to handle them. I have looked in to these three as being a good fit.

Would anyone be able to help me with what are easy and accessible offerings? Things I could get at a grocery store.

I don't have access to incense at the moment. I'm planning on getting Ipos some nice bottled water, giving them a cup and drinking from one myself. I hope that would be a good offering for them.

Thanks in advance!
