Is there any kind of tax to store products delivered to the hotel? What if they are delivered directly to me?

If you are staying in the park hotels they will deliver items to your room, they will also send the to the front of the park, so you do not have to carry them around all day. No charge, just takes time.

If you staying in the hotel, I believe the stuff you buy at the park they will deliver to your room with no up charge

No

Thank you both, but the question is in regard to stuff bought outside The Park, be it via Amazon, BestBuy or similar.
