Here's what I have now:
Condition: Total number of items > 0
Condition: Total number of unique items in the cart AND
Condition: If Session variable exists:eCartCheckoutForm_shipping_country AND
??Set to US??
Calculation: Flat rate
Create a flat rate shipping of $5.00
So I've added "If Session variable exists:eCartCheckoutForm_shipping_country" to the rule, what would I put for the next Condition for it to be US only?
