Newbie here:
Can anyone help me try and figure out how to set up my Zen Cart Store Shipping.

I am using Paypal to process my store's payments so I'm not sure if I should be using Zen Cart Shipping or Paypal Shipping?

And I'm not sure how to set up my Shipping Tier - this is the Shipping I need to set up:

Shipping, handling, and insurance charges for items under $1000.00
Products A- $10.00
Products B- $15.00
Products C- $20.00
Products D- $20.00
Products E- $20.00

For items over $1000.00 additional insurance coverage is required.
Add $1.00 for each additional $100.00, $10.00 per $1000.00

Any help would be REALLY APPRECIATED!
