I am using only the Flat Rate shipping option for my online ordering at
http://www.zcater.com/onlinestore and it is working just as expected.
I have no button to select it because I have no other options.
- I did not have to select a shipping company. This was not a requirement, we do our own delivery.
This is how an order shows up in the confirmation page:
Sub-Total: $6.95
California sales tax rate (7.75%) + Service charge (15%): $1.58
Flat Rate (Delivery Charge): $6.95
Total: $15.48
It may be different if you have more than 1 option for shipping, but this works fine for me.
